Abu Hurairah narrated that :
the Messenger of Allah said: Indeed Allah accepts charity, and He accepts it with His Right (Hand) to nurture it for one of you, just like one of you would nuture his foal, until the bite (of food) becomes as large as Uhud. The Book of Allah, the Mighty and Sublime testifies to that: 'He accepts repentance from His worshipers, and accepts charity.'And: 'Allah will destroy Riba and give increase for charity.' (Abu Eisa) said: This Hadith is (Hasan) Sahih.
