Sa’id reported Sa’d came to the Prophet (SWAS) and asked him Which sadaqah do you like most? He replied Water.
Sunan Abi Dawud Book 9, Hadith 124
← Previous Hadith The Messenger of Allah (ﷺ) commanded us one day to give sadaqah. At that time I had some property. I said: Today I shall surpass AbuBakr if I surpass him any day. I, therefore, brought half my property. The Messenger of Allah (ﷺ) asked: What did you leave for your family? I replied: The same amount. AbuBakr brought all that he had with him. The Messenger of Allah (ﷺ) asked him: What did you leave for your family? He replied: I left Allah and His Apostle for them. I said: I shall never compete you in anything.
