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