It is narrated from Hazrat Abu Darda (may Allah be pleased with him) that a person asked the Holy Prophet (peace and blessings be upon him) about the ruling on accepting gifts and grants from a king. The Holy Prophet (peace and blessings be upon him) said: "Without asking and without desiring, whatever Allah grants you, accept it, and benefit from it."
