Sahih Al Bukhari Hadith Number 1295

Narrated ‘Amir bin Sa`d bin Abi Waqqas: That his father said, “In the year of the last Hajj of the Prophet (peace be upon him) I became seriously ill and the Prophet (peace be upon him) used to visit me inquiring about my health. I told him, ‘I am reduced to this state because of illness and I am wealthy and have no inheritors except a daughter, (In this narration the name of ‘Amir bin Sa`d is mentioned and in fact it is a mistake; the narrator is `Aisha bint Sa`d bin Abi Waqqas). Should I give two-thirds of my property in charity?’ He said, ‘No.’ I asked, ‘Half?’ He said, ‘No.’ then he added, ‘Onethird, and even one-third is much. You’d better leave your inheritors wealthy rather than leaving them poor, begging others. You will get a reward for whatever you spend for Allah’s sake, even for what you put in your wife’s mouth.’ I said, ‘O Allah’s Messenger (peace be upon him)! Will I be left alone after my companions have gone?’ He said, ‘If you are left behind, whatever good deeds you will do will upgrade you and raise you high. And perhaps you will have a long life so that some people will be benefited by you while others will be harmed by you. O Allah! Complete the emigration of my companions and do not turn them renegades.’ But Allah’s Messenger (peace be upon him) felt sorry for poor Sa`d bin Khaula as he died in Mecca.” (but Sa`d bin Abi Waqqas lived long after the Prophet (peace be upon him).
