It is narrated from Hazrat Muawiyah (may Allah be pleased with him) that he heard the Prophet (peace and blessings of Allah be upon him) say: If a person’s paternal cousin asks him for an extra share of his wealth and he does not give it to him, then on the Day of Resurrection he will be turned into a bald snake which will chew up his extra share.
