narrated that the Messenger of Allah (ﷺ) said: "I have been ordered to fight the people until they say La Ilaha Illallah", and if they say that, then their blood and wealth will be protected from me, except what it makes obligatory upon them, and their reckoning is up to Allah."

said: "When the Messenger of Allah (ﷺ) died and Abu Bakr became the Khalifah after him, whoever disbelieved from the Arabs disbelieved, so Umar bin Al-Khattab said to Abu Bakr: 'How will you fight the people while the Messenger of Allah has said: 'I have been ordered to fight the people until they say La Ilaha Illallah, and if they say that, then their blood and wealth will be protected from me, except what it makes obligatory upon them, and their reckoning is with Allah?' So Abu Bakr said: 'By Allah I will fight whoever differentiates between Salat and Zakat. For indeed, Zakat is the right due upon wealth. And by Allah! If they withhold even (camel) tethers which they used to give to the Messenger of Allah (ﷺ) I will fight them for withholding it.' So Umar bin Al-Khattab said: 'By Allah! I saw that Allah had opened Abu Bakr's chest to fighting, so I knew that it was correct.'"

that the Messenger of Allah (ﷺ) said: "I have been ordered to fight the people until they bear witness to La Ilaha Illallah, and that Muhammad is His servant and Messenger, and they face our Qiblah, eat our slaughtered (meat), and perform our Salat. And if they do that, then their blood and wealth will be unlawful to us, except with its due right. For them shall be whatever is for the Muslims, and they shall be obliged with that which the Muslims are obliged."

that the Messenger of Allah (ﷺ) said: "Islam is based upon five: the testimony of La Ilaha Illallah, and that Muhammad is the Messenger of Allah, the establishment of the Salat, giving the Zakat, fasting (the month of) Ramadan, and performing Hajj to the House."

"The first person to speak about Al-Qadar was Ma'bad Al-Juhani." He said: "Humaid bin Abdur-Rahman Al-Himyari and I went out until we reached Al-Madinah, and we said: 'If we could only meet someone among the companions of the Prophet (ﷺ) so we could ask him about what those people have innovated." [He said:] "So we met him - meaning Abdullah bin 'Umar - while he was leaving the Masjid." [He said:] "My companion and I were on either side of him." [He said:] I thought my companion was going to leave the speaking to me so I said: "O Abu Abdur-Rahman! There is a group of people who recite the Qur'an and seek knowledge, and they claim there is no Al-Qadar, and that the affair is left to chance.' He said: "Whenever you meet those people, then tell them that I am not of them and they are not of me. By the One Whom Abdullah swears by! If one of them were to spend gold the like of Uhud (mountain) in charity, it would not be accepted from him until he believes in Al-Qadar; the good of it and the bad of it.'" He said: "Then he began to narrate, he said: "'Umar bin Al-Khattab said: "We were with the Messenger of Allah when a man came with extremely white garments, and extremely black hair. He had no appearance of traveling visible on him, yet none of us recognized him. He came until he reached the Prophet (ﷺ). He put his knees up against his knees, and then said: "O Muhammad! What is Iman?' He said 'To believe in Allah, His Angels, His, Books, His Messengers, the Day of Judgement, and Al-Qadar, the good of it and the bad of it.' He said: 'Then what is Islam?' He said: 'Testifying to La Ilaha Illallah, and that Muhammad is His servant and Messenger, establishing the Salat, giving the Zakat, performing Hajj to the House, and fasting (the month of) Ramadan.' He said: 'Then what is Ihsan?' He said 'That (is) you worship Allah as if you see Him, and although you do not see Him, He certainly sees you.' He said: 'For all of those he replied to him: 'You have told the truth.'" He said: "So we were amazed at him, he would ask, and then tell him that he is telling the truth. He said: 'Then when is the Hour?' He (ﷺ) said: 'The one being asked knows no more than the questioner.' He said: 'Then what are its signs?' He said: 'That the slave woman gives birth to her master, and that the naked, poor, and bare-footed shepherds rival each other in the height of the buildings.'" 'Umar said: 'Then the Prophet (ﷺ) met me three days after that and said: 'O 'Umar! Do you know who the questioner was? It was Jibril. He came to teach you about the matters of your religion.'"

"A delegation of Abdul-Qais came to the Messenger of Allah (ﷺ) and said: 'We are a tribe from Rabi'ah, and we cannot come to you except during the sacred months. So order us with something that we can take from you, and then we call those who are behind us to it.'So he said: 'I order you with four things: To testify to La Ilaha Illallah, and that I am the Messenger of Allah; to establish the Salat, to give the Zakat, and to give the Khumus from the spoils of war that you gain.'"

that the Messenger of Allah (ﷺ) said: "Indeed among the believers with the most complete faith is the one who is the best in conduct, and the most kind to his family."

that the Messenger of Allah (ﷺ) delivered a Khtubah in which he exhorted them, then he said: "O women! Give charity for you are the majority of the people of the Fire." A woman among them said: "And why is that O Messenger of Allah?" He said: "Because of your cursing so much." - meaning your ungratefulness towards your husbands. He said: "And I have not seen any among those lacking in intellect and religion who are more difficult upon people possessing reason and insight than you." A woman among them said: "And what is the deficiency of her intellect and religion?" He said: "The testimony of two women among you is like the testimony of a man, and the deficiency in your religion is menstruation, because one of you will go three or four days without performing Salat."

that the Messenger of Allah (ﷺ) said: "Faith has seventy-some odd doors, the lowest of which is removing something harmful from the road, and its highest is the statement 'La Ilaha Illallah.'"

that the Messenger of Allah (ﷺ) passed by a man and he was chastising his brother about modesty, so the Messenger of Allah (ﷺ) said: "Al-Haya' is part of faith."

"I accompanied the Prophet (ﷺ) on a journey. One day I was near him while we were moving so I said: 'O Messenger of Allah! Inform me about an action by which I will be admitted into Paradise, and which will keep me far from the Fire.' He said: 'You have asked me about something great, but it is easy for whomever Allah makes it easy: Worship Allah and do not associate any partners with Him, establish the Salat, give the Zakat, fast Ramadan and perform Hajj to the HOuse.' Then he said: 'Shall I not guide you to the doors of good? Fasting is a shield, and charity extinguishes sins like water extinguishes fire - and a man's praying in depths of the night.'" He said: "Then he recited: 'Their sides forsake their beds to call upon their Lord.' Until he reached: 'What they used to do.' [32:16-17]Then he said: 'Shall I not inform you about the head of the entire matter, and its pillar, and its hump?' I said: 'Of course O Messenger of Allah! He said: 'The head of the matter is Islam, and its pillar is the Salat, and its hump is Jihad.' Then he said: 'Shall I not inform you about what governs all of that?' I said: 'Of course O Messenger of Allah!'" He (ﷺ) said: "So he grabbed his tongue. He said 'Restrain this.' I said: 'O Prophet of Allah! Will we be taken to account for what we say?' He said: 'May your mother grieve your loss O Mu'adh! Are the people tossed into the Fire upon their faces, or upon their noses, except because of what their tongues have wrought'"

that the Messenger of Allah (ﷺ) said: "If you see a man who comes to the Masjid then bear witness to his faith." Because Allah, the Exalted, says: Only those who believe in Allah, and the Last Day, and establish the Salat, and give the Zakat (should) maintain the Masajid until the end of the Ayah (9:18)

that the Prophet (ﷺ) said: "Between disbelief and faith is abandoning the Salat."

Similar to the previous chain and said: "Between a slave and Shirk or disbelief is abandoning the Salat."

that the Messenger of Allah (ﷺ) said: "Between a slave of Allah and disbelief is abandoning the Salat."

that the Messenger of Allah (ﷺ) said: "The covenant between us and them is the Salat, so whoever abandons it he has committed disbelief."

The Companions of Muhammad (ﷺ) didn't consider leaving anything to be disblief except for the Salat.

that he heard the Messenger of Allah (ﷺ) say: "Whoever is pleased with Allah as (his) Lord, and Islam as (his) religion, and Muhammad as (his) Prophet, then he has tasted the sweetness of faith."

that the Messenger of Allah (ﷺ) said: "There are three things for which whomever has them, then he has tasted the sweetness of faith: The one for whom Allah and His Messenger are more beloved than anything else; whoever loves someone and he does not love him except for the sake of Allah, and whoever hates to return to disbelief after Allah has saved him from it, just as he hates to be thrown into fire."
