The Prophet (ﷺ) said about the Ansar: "Only a believer loves them, and only a hypocrite hates them. Allah loves him who loves them and Allah hates him who hates them".[Al-Bukhari and Muslim].

Messenger of Allah (ﷺ) said, "Allah, the Exalted, has said: 'For those who love one another for the sake of My Glory, there will be seats of light (on the Day of Resurrection), and they will be envied by the Prophets and martyrs".[At- Tirmidhi, who classified it as Hadith Hasan Sahih].

I once entered the mosque in Damascus. I happened to catch sight of a young man who had bright teeth (i.e., he was always seen smiling). A number of people had gathered around him. When they differed over anything they would refer it to him and act upon his advice. I asked who he was and I was told that he was Mu'adh bin Jabal (May Allah be pleased with him) The next day I hastened to the mosque, but found that he had arrived before me and was busy in performing Salat. I waited until he finished, and then went to him from the front, greeted him with Salam and said to him, "By Allah I love you." He asked, "For the sake of Allah?" I replied, "Yes, for the sake of Allah". He again asked me, "Is it for Allah's sake?" I replied, "Yes, it is for Allah's sake." Then he took hold of my cloak, drew me to himself and said, "Rejoice,! I heard Messenger of Allah (ﷺ) saying, 'Allah, the Exalted, says: My love is due to those who love one another for My sake, meet one another for My sake, visit one another for My sake and spend in charity for My sake".[Malik].

The Prophet (ﷺ) said, "When a man loves his brother (for Allah's sake) let him tell him that he loves him".[Abu Dawud and At- Tirmidhi, who classified it as Hadith Sahih].

Messenger of Allah (ﷺ) held my hand and said, "O Mu'adh, By Allah, I love you and advise you not to miss supplicating after every Salat (prayer) saying: 'Allahumma a'inni 'ala dhikrika wa shukrika, wa husni 'ibadatika,' (O Allah, help me remember You, expressing gratitude to You and worship You in the best manner)".[Hadith Sahih].[Abu Dawud and An- Nasa'i].

A man was with the Prophet (ﷺ) when another man passed by and the former said: "O Messenger of Allah! I love this man (for Allah's sake)". Messenger of Allah (ﷺ) asked, "Have you informed him?" He said, "No". Messenger of Allah (ﷺ) then said, "Tell him (that you love him)". So he went up to the man and said to him, "I love you for the sake of Allah;" and the other replied, "May Allah, for Whose sake you love me, love you."[Abu Dawud].

Messenger of Allah (ﷺ) said, "Allah, the Exalted, has said: 'I will declare war against him who treats with hostility a pious worshipper of Mine. And the most beloved thing with which My slave comes nearer to Me, is what I have enjoined upon him; and My slave keeps on coming closer to Me through performing Nawafil (voluntary prayers or doing extra deeds besides what is obligatory) until I love him, (so much so that) I become his hearing with which he hears, and his sight with which he sees, and his hand with which he strikes, and his leg with which he walks; and if he asks Me something, I will surely give him, and if he seeks My Protection (refuge), I will surely protect him".[Al-Bukhari]

The Prophet (ﷺ) said, "When Allah loves a slave, calls out Jibril and says: 'I love so-and-so; so love him'. Then Jibril loves him. After that he (Jibril) announces to the inhabitants of heavens that Allah loves so- and-so; so love him; and the inhabitants of the heavens (the angels) also love him and then make people on earth love him".[Al- Bukhari and Muslim].Another narration of Muslim is: Messenger of Allah, (ﷺ) said: "When Allah loves a slave, He calls Jibril (Gabriel) and says: 'I love so-and-so; so love him.' And then Jibril loves him. Then he (Jibril) announces in the heavens saying: Allah loves so-and-so; so love him; then the inhabitants of the heavens (the angels) also love him; and then people on earth love him. And when Allah hates a slave, He calls Jibril and says: 'I hate so- and-so, so hate him.' Then Jibril also hates him. He (Jibril) then announces amongst the inhabitants of heavens: 'Verily, Allah hates so- and-so, so you also hate him.' Thus they also start to hate him. Then he becomes the object of hatred on the earth also".[Muslim].

Messenger of Allah, (ﷺ) appointed a man in charge of an army unit who led them in Salat (prayer); he always concluded his recitation with Surat Al-Ikhlas: "Say (O Muhammad (ﷺ)): 'He is Allah, (the) One. Allah-us-Samad (Allah - the Self-Sufficient). He begets not, nor was He begotten. And there is none equal or comparable to Him."' (112:1-4) Upon their return to Al-Madinah, they mentioned this to Messenger of Allah (ﷺ), who said, "Ask him why he does so?" He was asked and he said, "This Surah contains the Attributes of Allah, the Gracious, and I love to recite it. Messenger of Allah (ﷺ) then told them, "Tell him that Allah loves him".[Al-Bukhari and Muslim].

Messenger of Allah (ﷺ) said, "He who performs the Fajr (dawn) prayer comes under the Protection of Allah, so beware lest Allah questions you about what you owe Him. For if He questions anyone of you and he falls short of fulfilling the duty which he owes Him, He will requite and then throw upon his face into the Hellfire".[Muslim].

Messenger of Allah (ﷺ) said, "I have been commanded (by Allah) to fight people until they testify that there is no true god except Allah, and that Muhammad is the Messenger of Allah, and perform Salat and pay Zakat. If they do so, they will have protection of their blood and property from me except when justified by Islam, and then account is left to Allah".[Al-Bukhari and Muslim].

Messenger of Allah (ﷺ) said, "He who professes La ilaha illallah (There is no true god except Allah), and denies of everything which the people worship besides Allah, his property and blood become inviolable, and it is for Allah to call him to account".[Muslim].

I said, "Tell me, O Messenger of Allah, if I meet an infidel, and we fight together, and he cuts off my hands with his sword, then hides from me behind a tree and (then) says he has submitted himself to Allah. Shall I kill him after he has said it?" He (ﷺ) replied, "Do not kill him." I submitted, "But O Messenger of Allah, he cut off one of my hands and only then he said it." Messenger of Allah (ﷺ) then replied, "Do not kill him, for if you do so, he will be in the position in which you were before you killed him (i.e., he will be considered a Muslim and thus his life will be inviolable), and you will be in the position in which he was before he made his testimony (i.e., your life will not be inviolable, for his heirs can ask for Qisas)".[Al-Bukhari and Muslim].

Messenger of Allah (ﷺ) sent us to Huraqat, a tribe of Juhainah. We attacked that tribe early in the morning and defeated them, (then) a man from the Ansar and I caught hold of a man (of the defeated tribe). When we overcame him, he said: 'La ilaha illallah (There is no true god except Allah).' At that moment, the Ansari spared him, but I attacked him with my spear and killed him. By the time we went back to Al-Madinah, news had already reached Messenger of Allah (ﷺ). He said to me, "O Usamah, did you kill him after he professed La ilaha illallah (There is no true god except Allah)?" I said, "O Messenger of Allah! He professed it only to save his life." Messenger of Allah (ﷺ) repeated, "Did you kill him after he had professed La ilaha illallah?" He went on repeating this to me until I wished I had not embraced Islam before that day (so that I would have not committed this sin).[Al-Bukhari and Muslim].Another narration is: Messenger of Allah (ﷺ) said, "Did you kill him in spite of his professing La ilaha illallah?" I said, "O Messenger of Allah! He said out of fear of our arms." He (ﷺ) said, "Why did you not cut his heart open to find out whether he had done so sincerely or not?" He continued repeating it until I wished that I had embraced Islam only that day.

Messenger of Allah (ﷺ) dispatched a contingent of the Muslims to a tribe of the polytheists. The two sides met (in combat) at one place. A man among the polytheists was so dashing that, whenever he intended to kill a man from Muslims, he killed him. Amongst the Muslims, too, was a man looking forward to (an opportunity of) his (polytheist's) unmindfulness. He (the narrator) said: We talked that he was Usamah bin Zaid (May Allah be pleased with him). When he raised his sword, he (the soldier of the polytheists) uttered: "La ilaha illallah (There is no true god except Allah)." But he (Usamah bin Zaid) killed him. When the good news of victory reached Messenger of Allah (ﷺ) he asked him (about the events of the battle), and he informed him about the man (Usamah) and what he had done. He (Messenger of Allah (ﷺ)) sent for him and asked him why he had killed him. He (Usamah) said, "O Messenger of Allah, he struck the Muslims and killed such and such of them." And he named some of them. (He continued): "I attacked him and when he saw the sword he said: 'La ilaha illallah."' Messenger of Allah (ﷺ) said, "Did you kill him?" He (Usamah) replied in the affirmative. The Messenger of Allah then remarked, "What would you do with regard to (the utterance): La ilaha illallah, when it comes (before you) on the Day of Resurrection?" He (Usamah) said, "O Messenger of Allah! Beg forgiveness for me". He (the Prophet (ﷺ)) said, "What would you do with regard to (the utterance): La ilaha illallah, when it comes (before you) on the Day of Resurrection?" He (Messenger of Allah (ﷺ)) added nothing to it but kept repeating, "What would you do with regard to (the utterance): La ilaha illallah, when it comes (before you) on the Day of Resurrection?".[Muslim].

I heard 'Umar bin Al- Khattab (May Allah be pleased with him) reported saying: "In the lifetime of Messenger of Allah (ﷺ) some people were called to account through Revelation. Now Revelation has discontinued and we shall judge you by your apparent acts. Whoever displays to us good, we shall grant him peace and security, and treat him as a near one. We have nothing to do with his insight. Allah will call him to account for that. But whosoever shows evil to us, we shall not grant him security nor shall we believe him, even if he professed that his intention is good."[Al-Bukhari].

Messenger of Allah (ﷺ), the truthful and the receiver of the truth informed us, saying, "The creation of you (humans) is gathered in the form of semen in the womb of your mother for forty days, then it becomes a clinging thing in similar (period), then it becomes a lump of flesh like that, then Allah sends an angel who breathes the life into it; and (the angel) is commanded to record four things about it: Its provision, its term of life (in this world), its conduct; and whether it will be happy or miserable. By the One besides Whom there is no true god! Verily, one of you would perform the actions of the dwellers of Jannah until there is only one cubit between him and it (Jannah), when what is foreordained would come to pass and he would perform the actions of the inmates of Hell until he enter it. And one of you would perform the actions of the inmates of Hell, until there is only one cubit between him and Hell. Then he would perform the acts of the dwellers of Jannah until he would enter it."[Al- Bukhari and Muslim].

Messenger of Allah (ﷺ) said, "Hell will be brought on that Day (the Day of Resurrection) with seventy thousand bridles; and with every bridle will be seventy thousand angels, pulling it".[Muslim].

Messenger of Allah (ﷺ) said, "The least tortured man on the Day of Resurrection is one underneath whose feet will be placed two live coal, and his brain will be boiling, and he would think that he is the most tortured, while he is the least tortured".[Al-Bukhari and Muslim].

Prophet of Allah (ﷺ) said, "Among the people of Hell are there those who will be emersed in fire to their ankels, some to their knees, some to their waists, and some to their throats".[Muslim].
