Malik related to me from Yahya ibn Said from Abu'l-Hubab Said ibn
Yasar that the Messenger of Allah, may Allah bless him and grant him
peace, said, "Whoever gives sadaqa from good earning - and Allah only
accepts the good - it is as if he placed it in the palm of the
Merciful to raise it, as one of you raises his foal or young camel
until it is like the mountain "
Muwatta Malik Book 58, Hadith 1
