It is also narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever among the believers gives charity from lawful and pure earnings—and Allah Almighty accepts only that which is pure, and only this lawful earning ascends towards the sky—then Allah Almighty takes this (charity) in His hand and keeps increasing it just as one of you raises his mare or calf, until a single date becomes as large as a great mountain.
