It is narrated from Hazrat Thawban (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Whoever guarantees me one thing, I will guarantee him Paradise. Hazrat Thawban (may Allah be pleased with him) offered himself. The Holy Prophet (peace and blessings be upon him) said: Do not ask people for anything. He replied: Alright. So after that, he never asked anyone for anything, even if he was riding and his whip fell, he would not ask anyone to pick it up; he would get down himself and pick it up.
