Saeed bin Musayyib (may Allah have mercy on him) says that once Amir Muawiyah (may Allah be pleased with him) came to Madinah Munawwarah and delivered a sermon to us, in which he took out a lock of hair and showed it, and said: "I think only the Jews do this. When the Prophet (peace and blessings of Allah be upon him) learned of this, he called it falsehood."
