Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "It is not permissible for a Muslim who has something to bequeath to stay for two nights without having his will written with him."

Narrated Sayyiduna Amr bin Harith (the brother of the Mother of the Believers, Juwayriya bint Harith, may Allah be pleased with her, who was the sister-in-law of the Messenger of Allah, peace and blessings be upon him): The Messenger of Allah, peace and blessings be upon him, at the time of his death, did not leave behind any dirham or dinar, nor any slave, nor any slave-girl, nor anything else except his white mule, his weapons, and a piece of land which he had given as charity.

It was asked from Sayyiduna Abdullah bin Abi Awfa (may Allah be pleased with him) whether the Prophet (peace and blessings of Allah be upon him) made any bequest (wasiyyah)? He said: No. It was asked: Then how was bequest made obligatory or how was he commanded to make a bequest? He said: The Prophet (peace and blessings of Allah be upon him) made a bequest to act upon the Book of Allah.

Narrated Abu Huraira (may Allah be pleased with him):
A man asked the Prophet (peace and blessings of Allah be upon him), "Which charity is best?" He (peace be upon him) replied: "That you give charity while you are healthy, desiring wealth, hoping for affluence, and fearing poverty. Do not delay charity until the soul reaches the throat, and then you say, 'Give this much to so-and-so and this much to so-and-so,' while by then it has already become the property of so-and-so (i.e., your heir)."

Narrated Abu Huraira (may Allah be pleased with him): When Allah revealed this verse: "And warn your nearest kindred" (Ash-Shu'ara: 216), the Messenger of Allah (peace and blessings of Allah be upon him) stood up and said: "O people of Quraish! (or he said something similar), save yourselves! I cannot save you from Allah (His punishment). O Banu Abd Manaf! I cannot save you from Allah (His punishment). O Abbas bin Abdul Muttalib! I cannot save you from Allah (His punishment). O Safiyyah, the aunt of the Messenger of Allah (peace and blessings of Allah be upon him)! I cannot save you from Allah (His punishment). And O Fatimah al-Zahra, daughter of Muhammad (peace and blessings of Allah be upon him)! Take whatever you want from my wealth, but I cannot save you from Allah (His punishment)."

Narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that his father (the Commander of the Faithful, Umar bin Khattab, may Allah be pleased with him) donated a property (a garden) named Thamgh in the time of the Messenger of Allah (peace and blessings of Allah be upon him). So Sayyiduna Umar (may Allah be pleased with him) submitted: "O Messenger of Allah! I have acquired a property and it is very precious to me. I wish to give it in charity." The Noble Prophet (peace and blessings of Allah be upon him) said: "Give away the original trees as charity on the condition that they are neither sold, nor gifted, nor inherited, but its fruits are spent in the way of Allah." Thus, Sayyiduna Umar (may Allah be pleased with him) gave it in charity on this condition, so that its income would be spent on warriors in the cause of Allah, freeing slaves, the needy, guests, travelers, and relatives. (And he also said that) whoever is its caretaker, there is no sin upon him if he eats from it according to custom or feeds his friend, provided that he does not intend to accumulate wealth by this act.

Narrated Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him) that he said: "Avoid the seven destructive sins." The people asked, "O Messenger of Allah! What are they?" He (peace be upon him) said: "(1) Associating partners with Allah, (2) Practicing magic, (3) Killing a soul which Allah has forbidden except by right, (4) Consuming usury, (5) Consuming the property of an orphan, (6) Fleeing from the battlefield, (7) Accusing chaste, innocent, believing women of adultery."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "My heirs should not distribute dinars nor dirhams; whatever I leave after providing for my wives and paying the wages of the caretaker of my property, that is charity."

When our master Uthman bin Affan (may Allah be pleased with him) was besieged, he climbed to a high place and appeared before the rebels and said, "I ask you by Allah, and I give this oath only to the companions of the Prophet (peace and blessings of Allah be upon him), do you not know that the Messenger of Allah (peace and blessings of Allah be upon him) said: 'Whoever buys the well of Rumah (by name) and dedicates it for the Muslims, he will be granted Paradise.' So I bought it (and dedicated it). Do you not know that the Prophet (peace and blessings of Allah be upon him) said: 'Whoever equips the warriors for the Battle of Tabuk, he will be granted Paradise.' So I provided the equipment." (The narrator) says that the companions (may Allah be pleased with them) affirmed Uthman (may Allah be pleased with him).

Narrated Ibn Abbas (may Allah be pleased with them) that a man from the tribe of Bani Sahm set out on a journey with Tamim Dari and Adi bin Badda (may Allah be pleased with them). Then he died in a land where there was no Muslim. When Tamim and Adi (may Allah be pleased with them) brought his inheritance, a silver cup with golden engravings was missing. So the Messenger of Allah (peace and blessings of Allah be upon him) made both of them swear an oath, and they swore. After that, the cup was found in Mecca with some people who said, "We bought it from Tamim and Adi." Then two men from the relatives of the deceased stood up and swore an oath that "Our testimony is more acceptable than the testimony of both of them. We testify that this cup belongs to our (deceased) relative." (Ibn Abbas, may Allah be pleased with them, says) that this verse was revealed concerning them: "O you who believe! When death approaches any of you, let two just men from among you act as witnesses at the time of making the will, or two others from outside if you are traveling through the land and the calamity of death befalls you..." until the end of the verse.
