Umar acquired a land at Khaibar. He came to Allah's Apostle (ﷺ) and sought his advice in regard to it. He said: Allah's Messenger, I have acquired land in Khaibar. I have never acquired property more valuable for me than this, so what do you command me to do with it? Thereupon he (Allah's Apostle) said: If you like, you may keep the corpus intact and give its produce as Sadaqa. So 'Umar gave it as Sadaqa declaring that property must not be sold or inherited or given away as gift. And Umar devoted it to the poor, to the nearest kin, and to the emancipation of slaves, aired in the way of Allah and guests. There is no sin for one, who administers it if he eats something from it in a reasonable manner, or if he feeds his friends and does not hoard up goods (for himself). He (the narrator) said: I narrated this hadith to Muhammad, but as I reached the (words)" without hoarding (for himself) out of it." he (Muhammad' said:" without storing the property with a view to becoming rich." Ibn 'Aun said: He who read this book (pertaining to Waqf) informed me that in it (the words are)" without storing the property with a view to becoming rich."
Sahih Muslim Book 25, Hadith 21
The Messenger of Allah (ﷺ) came out in the year of al-Hudaibbiyyah with over ten hundreds of Companions and when he came to Dhu al Hulaifah. He garlanded and marked the sacrificial animals, and entered the sacred state of Umrah. He then went on with the tradition. The Prophet moved on and when he came to the mountain, pass by which one descends (to Mecca) to them, his riding-beast knelt down, and the people said twice: Go on, go on, al-Qaswa has become jaded. The Prophet (May peace be upon him) said: She has not become jaded and that is not a characteristic of hers, but He Who restrained the elephant has restrained her. He then said: By Him in Whose hand my soul is, they will not ask any me good thing by which they honor which God has made sacred without my giving them it. He then urged her and she leaped up and he turned aside from them, and stopped at the farthest side of al-Hudaibiyyah at a pool with little water. Meanwhile Budail bin Warqa al-Khuza’I came, and ‘Urwah bin Mas’ud joined him. He began to speak to the Prophet (ﷺ). Whenever he spoke to the Prophet (ﷺ), he caught his beard. Al Mughriah bin Shu’bah was standing beside the Prophet (ﷺ).He had a sword with him, wearing a helmet. He (Al Mughriah) struck his (‘Urwah’s) hand with the lower end of his sheath, and said: Keep away your hand from his beard. ‘Urwah then raised his hand and asked: Who is this? They replied: Al-Mughirah bin Shu’bah. He said: O treacherous one! Did I not use my offices in your treachery? In pre-Islamic days Al-Mughirah bin Shu’bah accompanied some people and murdered them, and took their property. He then came (to the Prophet) and embraced Islam. The Prophet (ﷺ) said: As for Islam we accepted it, but as to the property, as it has been taken by treachery, we have no need of it. He went on with the tradition the Prophet (ﷺ) said: Write down: This is what Muhammad, the Messenger of Allah, has decided. He then narrated the tradition. Suhail then said: And that a man will not come to you from us, even if he follows your religion, without you sending him back to us. When he finished drawing up the document, the Prophet (ﷺ) said to his Companions: Get up and sacrifice and then shave. Thereafter some believing women who were immigrants came. (Allah sent down: O yea who believe, when believing women come to you as emigrants). Allah most high forbade them to send them back, but ordered them to restore the dower. He then returned to Medina. Abu Basir a man from the Quraish (who was a Muslim), came to him. And they sent (two men) to look for him; so he handed him over to the two men. They took him away, and when they reached Dhu Al Hulaifah and alighted to eat some dates which they had, Abu Basir said to one of the men : I swear by Allah so-and-so, that I think this sword of yours is a fine one; the other drew the sword and said : Yes I have tried it. Abu Basir said: Let me look at it. He let him have it and he struck him till he died, whereupon the other fled and came to Medina, and running entered the mosque. The Prophet ( may peace be upon him) said: This man has seen something frightful. He said: I swear by Allah that my Companion has been killed, and im as good as dead. Abu Basir then arrived and said: Allah has fulfilled your covenant. You returned me to them, but Allah saved me from them. The Prophet (ﷺ) said: Woe to his mother, stirrer up of war! Would that he had someone (i.e. some kinsfolk). When he heard that he knew that he would send him back to them, so he went out and came to the seashore. Abu Jandal escaped and joined Abu Basir till a band of them collected.
Sunan Abi Dawud Book 15, Hadith 289
'Adba belonged to a man of Banu 'Aqil. It used to go ahead of pligrims. The man was then captivated. He was brought in chains to the Prophet (ﷺ). The Prophet (ﷺ) was riding on a donkey with a blanket on him. He said: Muhammad, why do you arrest me and capture the one (i.e. the she-camel) which goes ahead of the pilgrims. He replied: We are arresting you on account of the crime committed by your allies Thaqid. Thaqif captivated two persons from among the Companions of the Prophet (ﷺ). He said (whatever he said) I am a Muslim, or he said: I have embraced Islam. When the Prophet (ﷺ) went ahead, he called him: O Muhammed, O Muhammed. Abu Dawud said: I learnt it from the version of the narrator Muhammad b. 'Isa. The Prophet (ﷺ) was compassionate and kind hearted. So he returned to him, and asked: What is the matter with you ? He replied: I am a Muslim. He said: Had you said it when the matter was in your hand, you would have succeeded completely. Abu Dawud said: I then returned to the version of the narrator Sulaiman (b. Harb). He said: Muhammad, I am hungry, so feed me. I am thirsty, so give me water. The Prophet (ﷺ) said: This is your need, or he said: This is his need (the narrator is doubtful). Later on the man was taken back (by Thaqif) as a ransom for the two men (of the Companions of the Prophet). The Prophet (ﷺ) retained 'Adba for his journey. The narrator said: The polytheists raided the pasturing animals of Medina and they took away 'Adba. When they took away 'Adba, they also captivated a Muslim woman. They used to leave their camels in the fields for rest at night. One night they slept and the (Muslim) woman stood up. Any camel on which she put her hand brayed until she came to 'Adba. She came to a she-camel which was docile and experienced. She then rode on her and vowed to Allah that if He saved her, she would sacrifice it. When she came to Medina, the people recognized the she-camel of the Prophet (ﷺ). The Prophet (ﷺ) was then informed about it and he sent for her. She was brought to him and she informed him about her vow. He said: It is a bad return that you have given it. Allah has not saved you, on its (back) that you now sacrifice it. A vow to do an act of disobedience must not be fulfilled, or to do something over which one has no control.
Abu Dawud said: This woman was the wife of Abu Dharr.
