It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: At one of the gates of the sky, an angel is appointed who says: Who is there who will give a loan so that he may be rewarded for it tomorrow? And at another gate, an angel says: O Allah, grant a substitute to the one who spends, and quickly destroy the wealth of the one who withholds.
