Muhammad bin Abi Fadayk محمد بن إسماعيل بن مسلم بن أبي فديك · Wills (Kitab Al-Wasaya)

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.
