The Prophet (ﷺ) said, "O Mu`adh! Do you know what Allah's Right upon His slaves is?" I said, "Allah and His Apostle know best." The Prophet (ﷺ) said, "To worship Him (Allah) Alone and to join none in worship with Him (Allah). Do you know what their right upon Him is?" I replied, "Allah and His Apostle know best." The Prophet (ﷺ) said, "Not to punish them (if they do so).

We were with the Prophet (ﷺ) when suddenly there came to him a messenger from one of his daughters who was asking him to come and see her son who was dying. The Prophet (ﷺ) said (to the messenger), "Go back and tell her that whatever Allah takes is His, and whatever He gives is His, and everything with Him has a limited fixed term (in this world). So order her to be patient and hope for Allah's reward." But she sent the messenger to the Prophet (ﷺ) again, swearing that he should come to her. So the Prophet got up, and so did Sa`d bin 'Ubada and Mu`adh bin Jabal (and went to her). When the child was brought to the Prophet (ﷺ) his breath was disturbed in his chest as if it were in a water skin. On that the eyes of the Prophet (ﷺ) became flooded with tears, whereupon Sa`d said to him, "O Allah's Messenger (ﷺ)! What is this?" The Prophet (ﷺ) said, "This is mercy which Allah has put in the heart of His slaves, and Allah bestows His mercy only on those of His slaves who are merciful (to others)."

The Prophet (ﷺ) said, "None is more patient than Allah against the harmful and annoying words He hears (from the people): They ascribe children to Him, yet He bestows upon them health and provision .

The Prophet (ﷺ) said, "The keys of the unseen are five and none knows them but Allah: (1) None knows (the sex) what is in the womb, but Allah: (2) None knows what will happen tomorrow, but Allah; (3) None knows when it will rain, but Allah; (4) None knows where he will die, but Allah (knows that); (5) and none knows when the Hour will be established, but Allah."

The Prophet (ﷺ) said, "On the Day of Resurrection Allah will hold the whole earth and fold the heaven with His right hand and say, 'I am the King: where are the kings of the earth?" '

Allah's Messenger (ﷺ) said, "Allah has ninety-nine Names, one-hundred less one; and he who memorized them all by heart will enter Paradise." To count something means to know it by heart.

The Prophet (ﷺ) said, "Do not swear by your fathers; and whoever wants to swear should swear by Allah."

Allah's Messenger (ﷺ) sent ten persons to bring the enemy's secrets and Khubaib Al-Ansari was one of them. 'Ubaidullah bin 'Iyad told me that the daughter of Al-Harith told him that when they gathered (to kill Khubaib Al Ansari) he asked for a razor to clean his pubic region, and when they had taken him outside the sanctuary of Mecca in order to kill him, he said in verse, "I don't care if I am killed as a Muslim, on any side (of my body) I may be killed in Allah's Cause; for that is for the sake of Allah's very Self; and if He will, He will bestow His Blessings upon the torn pieces of my body." Then Ibn Al-Harith killed him, and the Prophet (ﷺ) informed his companions of the death of those (ten men) on the very day they were killed.

The Prophet (ﷺ) said, "Allah did not send any prophet but that he warned his nation of the one-eyed liar (Ad-Dajjal). He is one-eyed while your Lord is not one-eyed, The word 'Kafir' (unbeliever) is written between his two eyes."

The Prophet (ﷺ) said, "Allah will gather the believers on the Day of Resurrection in the same way (as they are gathered in this life), and they will say, 'Let us ask someone to intercede for us with our Lord that He may relieve us from this place of ours.' Then they will go to Adam and say, 'O Adam! Don't you see the people (people's condition)? Allah created you with His Own Hands and ordered His angels to prostrate before you, and taught you the names of all the things. Please intercede for us with our Lord so that He may relieve us from this place of ours.' Adam will say, 'I am not fit for this undertaking' and mention to them the mistakes he had committed, and add, "But you d better go to Noah as he was the first Apostle sent by Allah to the people of the Earth.' They will go to Noah who will reply, 'I am not fit for this undertaking,' and mention the mistake which he made, and add, 'But you'd better go to Abraham, Khalil Ar-Rahman.' They will go to Abraham who will reply, 'I am not fit for this undertaking,' and mention to them the mistakes he made, and add, 'But you'd better go to Moses, a slave whom Allah gave the Torah and to whom He spoke directly' They will go to Moses who will reply, 'I am not fit for this undertaking,' and mention to them the mistakes he made, and add, 'You'd better go to Jesus, Allah's slave and His Apostle and His Word (Be: And it was) and a soul created by Him.' They will go to Jesus who will say, 'I am not fit for this undertaking, but you'd better go to Muhammad whose sins of the past and the future had been forgiven (by Allah).' So they will come to me and I will ask the permission of my Lord, and I will be permitted (to present myself) before Him. When I see my Lord, I will fall down in (prostration) before Him and He will leave me (in prostration) as long as He wishes, and then it will be said to me, 'O Muhammad! Raise your head and speak, for you will be listened to; and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then raise my head and praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit whom I will admit into Paradise. I will come back again, and when I see my Lord (again), I will fall down in prostration before Him, and He will leave me (in prostration) as long as He wishes, and then He will say, 'O Muhammad! Raise your head and speak, for you will be listened to; and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit to whom I will admit into Paradise, I will return again, and when I see my Lord, I will fall down (in prostration) and He will leave me (in prostration) as long as He wishes, and then He will say, 'O Muhammad! Raise your head and speak, for you will be listened to, and ask, for you will be granted (your request); and intercede, for your intercession will be accepted.' I will then praise my Lord with certain praises which He has taught me, and then I will intercede. Allah will allow me to intercede (for a certain kind of people) and will fix a limit to whom I will admit into Paradise. I will come back and say, 'O my Lord! None remains in Hell (Fire) but those whom Qur'an has imprisoned therein and for whom eternity in Hell (Fire) has become inevitable.' " The Prophet (ﷺ) added, "There will come out of Hell (Fire) everyone who says: 'La ilaha illal-lah,' and has in his heart good equal to the weight of a barley grain. Then there will come out of Hell (Fire) everyone who says: ' La ilaha illal-lah,' and has in his heart good equal to the weight of a wheat grain. Then there will come out of Hell (Fire) everyone who says: 'La ilaha illal-lah,' and has in his heart good equal to the weight of an atom (or a smallest ant).

The Prophet (ﷺ) sent Mu'adh to Yemen.

A man heard another man reciting (in the prayers): 'Say (O Muhammad): "He is Allah, the One." (112.1) And he recited it repeatedly. When it was morning, he went to the Prophet (ﷺ) and informed him about that as if he considered that the recitation of that Sura by itself was not enough. Allah's Messenger (ﷺ) said, "By Him in Whose Hand my life is, it is equal to one-third of the Qur'an."

Abu Bakr As-Siddiq said to the Prophet (ﷺ) "O Allah's Messenger (ﷺ)! Teach me an invocation with which I may invoke Allah in my prayers." The Prophet (ﷺ) said, "Say: O Allah!

When the Prophet (ﷺ) went to bed, he used to say, "Allahumma bismika ahya wa amut." And when he woke up in the mornings he used to say, "Al-hamdu li l-lahi al-ladhi ahyana ba'da ma amatana wa ilaihi-nnushur."

Allah's Messenger (ﷺ) said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

The people said to the Prophet (ﷺ) , "O Allah's Messenger (ﷺ)! Here are people who have recently embraced Islam and they bring meat, and we do not know whether they had mentioned Allah's Name while slaughtering the animals or not." The Prophet (ﷺ) said, "You should mention Allah's Name and eat."

when this Verse:--'Say (O Muhammad!): He has Power to send torments on you from above,' (6.65) was revealed; The Prophet (ﷺ) said, "I take refuge with Your Face." Allah revealed:-- '..or from underneath your feet.' (6.65) The Prophet (ﷺ) then said, "I seek refuge with Your Face!" Then Allah revealed:--'...or confuse you in party-strife.' (6.65) Oh that, the Prophet (ﷺ) said, "This is easier."

The Prophet (ﷺ) sent (an army unit) under the command of a man who used to lead his companions in the prayers and would finish his recitation with (the Sura 112): 'Say (O Muhammad): "He is Allah, the One." ' (112.1) When they returned (from the battle), they mentioned that to the Prophet. He said (to them), "Ask him why he does so." They asked him and he said, "I do so because it mentions the qualities of the Beneficent and I love to recite it (in my prayer)." The Prophet; said (to them), "Tell him that Allah loves him."
