Once, Hazrat Zaid bin Thabit (may Allah be pleased with him) went to meet Hazrat Amir Muawiyah (may Allah be pleased with him). He narrated a hadith to him. Hazrat Amir Muawiyah (may Allah be pleased with him) ordered a man to write it down, but Hazrat Zaid (may Allah be pleased with him) said that the Noble Prophet (peace and blessings be upon him) forbade writing down any of his hadith. So, he erased it.
