Sahih al-Bukhari Book 75, Hadith 28
Allah's Messenger (ﷺ) came to visit me during my ailment which had been aggravated during Hajjat-al-
Wada`. I said to him, "You see how sick I am. I have much property but have no heir except my only
daughter May I give two thirds of my property in charity?"! He said, "No." I said, "Half of it?" He
said, "No." I said "One third?" He said, "One third is too much, for to leave your heirs rich is better
than to leave them poor, begging of others. Nothing you spend seeking Allah's pleasure but you shall
get a reward for it, even for what you put in the mouth of your wife."
I visited the Prophet (ﷺ) while he was having a high fever. I touched him an said, "You have a very high fever" He said, "Yes, as much fever as two me of you may have." I said. "you will have a double reward?" He said, "Yes No Muslim is afflicted with hurt caused by disease or some other inconvenience, but that Allah will remove his sins as a tree sheds its leaves."
When Allah's Messenger (ﷺ) was on his death-bed and in the house there were some people among whom was `Umar bin Al-Khattab, the Prophet (ﷺ) said, "Come, let me write for you a statement after which you will not go astray." `Umar said, "The Prophet (ﷺ) is seriously ill and you have the Qur'an; so the Book of Allah is enough for us." The people present in the house differed and quarrelled. Some said "Go near so that the Prophet (ﷺ) may write for you a statement after which you will not go astray," while the others said as `Umar said. When they caused a hue and cry before the Prophet, Allah's Messenger (ﷺ) said, "Go away!" Narrated 'Ubaidullah: Ibn `Abbas used to say, "It was very unfortunate that Allah's Messenger (ﷺ) was prevented from writing that statement for them because of their disagreement and noise."
