Amir bin Sa'd reported on the authority of his father (Sa'd bin Abi Waqqas): Allah's Messenger ( صلی اللہ علیہ وسلم ) visited me in my illness which brought me near death in the year of Hajjat-ul-Wada' (Farewell Pilgrimage). I said: Allah's Messenger, you can well see the pain with which I am afflicted and I am a man possessing wealth, and there is none to inherit me except only one daughter. Should I give two-thirds of my property as Sadaqa? He said: No. I said: Should I give half (of my property) as Sadaqa? He said: No. He (further) said: Give one-third (in charity) and that is quite enough. To leave your heirs rich is better than to leave them poor, begging from people; that you would never incur an expense seeking therewith the pleasure of Allah, but you would be rewarded therefore, even for a morsel of food that you put in the mouth of your wife. I said: Allah's Messenger would I survive my companions? He (the Holy Prophet) said: If you survive them, then do such a deed by means of which you seek the pleasure of Allah, but you would increase in your status (in religion) and prestige; you may survive so that people would benefit from you, and others would be harmed by you. (The Holy Prophet) further said: Allah, complete for my Companions their migration, and not cause them to turn back upon their heels. Sa'd bin Khaula is, however, unfortunate. Allah's Messenger ( صلی اللہ علیہ وسلم ) felt grief for him as he had died in Makkah.

I (again) said: (Permit me) to give away half. He (again refused). I (again said): Then one-third. He (the Holy Prophet) observed silence after (I had asked permission to give away) one-third.
