"Allah’s Messenger (Allah bless him and give him peace) went out during an hour in which he did not usually go out, and in which no one used to meet him, but Abu Bakr came to him, so he said: “What has brought you forth, O Abu Bakr?” He replied: “I came out to meet Allah’s Messenger (Allah bless him and give him peace), behold his face, and greet him with the salutation of peace.” Shortly thereafter "Umar came along, so he said: “What has brought you forth, O 'Umar?” He replied: “Hunger, O Messenger of Allah!” He said (Allah bless him and give him peace): “I have also experienced some of that!” Then they went to the house of Ibn at-Tihan al-Ansari, who was owned many date palms and sheep, but who had no servants, so they did not find him. They therefore asked his wife: “Where is your mate?” She said: “He has gone to draw sweet water for us.” They did not have to wait long before Abu’l-Haitham brought a waterskin that he was carrying full, so he set it down, and came to embrace the Prophet (Allah bless him and give him peace), offering his father and his mother as ransom for him. Then he took them to his garden, and spread a carpet for them. Then he went to a date palm, brought a bunch of dates and set it down. The Prophet said (Allah bless him and give him peace): “Have you not selected for us some of its ripe dates?” He replied: “O Messenger of Allah, I intended to let you choose or prefer some of its ripe and its unripe dates,” so they ate dates and drank from that water. Then the Prophet said (Allah bless him and give him peace): “By the One in whose Hand is my soul, this is some of the gracious favor about which you shall be asked on the Day of Resurrection: cool shade, good dates and cold water!” Then Abu’l-Haitham went to make a meal for them, so the Prophet said (Allah bless him and give him peace): “Do not slaughter a milch-animal for us.” He therefore slaughtered a young she-goat or a young billy goat, and brought it to them, so they ate. The Prophet said (Allah bless him and give him peace): “Do you have a servant?” When the answer was “No,” he said: “If a prisoner of war comes to us, come to us!” Then he (Allah bless him and give him peace) was brought two captives, unaccompanied by a third. Abu’l-Haitham then came to him, and the Prophet said (Allah bless him and give him peace): “Choose from the pair of them,” so he said: “O Messenger of Allah, choose for me!” The Prophet said (Allah bless him and give him peace): “The person whose opinion is requested deserves to be trusted. Take this one, for I have seen him performing the ritual prayer, and expect well of him!” Abu l-Haitham then went to his wife and told her what Allah’s Messenger had said, so his wife said: “You cannot arrive at the truth of what the Prophet (Allah bless him and give him peace) said about him, except by setting him free!” He said: “He is free, then!” The Prophet said (Allah bless him and give him peace): “Allah has not sent any Prophet, nor any Caliph, without his having two intimate friends: one who commands him to do what is right and fair, and forbids him to do what is wrong and unfair, and one who will spare no effort to corrupt him. If one is wary of the evil companion, he will be preserved from harm.”

While we were in the company of the Messenger of Allah (ﷺ) in the early hours of the morning, some people came there (who) were barefooted, naked, wearing striped woolen clothes, or cloaks, with their swords hung (around their necks). Most of them, nay, all of them, belonged to the tribe of Mudar. The color of the face of the Messenger of Allah (ﷺ) underwent a change when he saw them in poverty. He then entered (his house) and came out and commanded Bilal (to pronounce Adhan). He pronounced Adhān and Iqāma, and he (the Prophet) observed prayer (along with his Companion) and then addressed (them reciting verses of the Qur'an): “O people, fear your Lord, Who created you from a single being” to the end of the verse, “Allah is ever a Watcher over you” (4:1). (He then recited) a verse of Sura Hashr: “Fear Allah, and let every soul consider that which it sends forth for the afterlife, and fear Allah …” (18). (Then the audience began to vie with one another in giving charity.) Some donated a dinar, others a dirham, still others clothes, some donated a sā' of wheat, some a sā' of dates; till he (the Prophet) said: (Bring) even if it is half a date. Then a person from among the Ansar came there with a money bag which his hands could scarcely lift; in fact, they could not (lift). Then the people followed continuously, till I saw two heaps of eatables and clothes, and I saw the face of the Messenger (ﷺ) glistening, like gold (on account of joy). The Messenger of Allah (ﷺ) said: He who sets a good precedent in Islam, there is a reward for him for this (act of goodness) and reward of that also who acted according to it subsequently, without any deduction from their rewards; and he who sets in Islam an evil precedent, there is upon him the burden of that, and the burden of him also who acted upon it subsequently, without any deduction from their burden.

'Ubayd ibn Hunayn related to him that Abu Musa said, "I asked permission three times to come in to 'Umar, but he did not give me permission and so I went away. He said, ''Abdullah, is it hard on you to be kept waiting at your door.' I said, 'I asked permission from you three times and you did not give me permission, so I went away (and we were commanded to do that).' 'Umar said, 'From whom did you hear this?' I replied, 'I heard it from the Prophet, may Allah bless him and grant him peace.' 'Umar said, 'Did you hear something from the Prophet, may Allah bless him and grant him peace, which I did not hear? If you do not bring me a clear proof, I will make an example of you!' Therefore I went to a group of Ansar who were sitting in the mosque. I asked them and they said, 'Does anyone doubt this?' I told them what 'Umar had said. They said, 'Only the youngest of us will go with you.' So Abu Sa'id al-Khudri - or Abu Mas'ud - went with me to 'Umar. He said, 'We went out with the Prophet, may Allah bless him and grant him peace, when he was going to Sa'd ibn 'Ubada. He gave the greeting, but Sa'd did not give permission. Then he greeted him a second time and then a third time, but Sa'd did not give him permission. So the Prophet said, 'We have done what we must.' Then he went back and Sa'd caught up to him and said, 'Messenger of Allah! By the One who sent you with the Truth, every time you greeted me, I heard and answered you, but I wanted to have a lot of greeting (peace) from you for me and the people of my house.'" Abu Musa said, "By Allah, I am a guardian of the hadith of the Messenger of Allah, may Allah bless him and grant him peace." 'Umar said, "Yes, but I wanted to make sure."
