The Messenger of Allah (ﷺ) as saying: It is the duty of a Muslim man who has something which is to be given as bequest not to have it for two nights without having his will written regarding it.

The Messenger of Allah (ﷺ) did not leave dinars, dirhams, camels and goats, nor did he leave will for anything.

On the authority of his father (Sa'd b. Abi Waqqas): When he (Sa'd) fell ill at Mecca (according to the version of Ibn Abi Kkalaf) - then the agreed version has: which brought him near to death - the Messenger of Allah (ﷺ) went to visit him. He said: Messenger of Allah, I have a large amount of property, and my daughter is my only heir. May I give two-thirds (of my property) as a sadaqah (charity)? He said: No. He asked: Then a half ? He replied: No. He asked: Then one-third ? He replied: (You may will away) a third and third is a lot. To leave your heirs rich is better than to leave them poor begging from people. You will not spend anything, seeking thereby to please Allah, without being rewarded for it, even the mouthful you give your wife. I said: Messenger of Allah, shall I be left behind form immigration (to Medina)? He said: If you remain behind after me and do good works seeking the pleasure of Allah, your rank will be raised and degree increased. Perhaps you will not remain behind, and some people will benefit from you and others will be harmed by you. He then said: O Allah, complete the immigration of my Companions and do not turn them back. But miserable was Sa'd b. Khawlah. The Messenger of Allah (ﷺ) lamented on him as he died at Mecca.

A man asked the Messenger of Allah (ﷺ): Messenger of Allah, which sadaqah (charity) is the best ? He replied: (The best sadaqah is) that you give something as sadaqah (charity) when you are healthy, greedy, expect survival and fear poverty, and not that you postpone it until your death. and then you say: For so-and-so is such-and-such, and for so-and-so is such-and-such, while it was already for so-and-so.

The Prophet (ﷺ) said: A man giving a dirham as sadaqah (charity) during his life is better than giving one hundred dirhams as sadaqah (charity) at the moment of his death.

The Prophet (ﷺ) said: A man or a woman acts in obedience to Allah for sixty years, then when they are about to die they cause injury by their will, so they must go to Hell. Then Abu Hurayrah recited: "After a legacy which you bequeath or a debt, causing no injury...that will be the mighty success. Abu Dawud said: Al-Ash'ath b. Jabir is the grandfather of Nasr b. 'Ali.

The Messenger of Allah (ﷺ) said to me: Abu Dharr, I see you weak, and I like for you what I like for myself. Do not be a leader of two (persons), and do not be a guardian of an orphan. Abu Dawud said: This has been narrated only by the people of Egypt.
