It is narrated from Hazrat Abu Zaid (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) asked for water. I brought water in a bowl, and there was a hair in it which I removed. The Holy Prophet (peace and blessings be upon him) said, "O Allah! Grant him beauty." The narrator says that I saw Hazrat Abu Zaid (may Allah be pleased with him) at the age of 94, and there was not a single white hair in his beard.
