It is narrated from Hazrat Anas (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) arrived in Madinah Munawwarah, Hazrat Umm Sulaim (may Allah be pleased with her) took my hand and brought me to the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah (peace and blessings be upon him)! This is my son and he knows how to write." Thus, I served the Prophet (peace and blessings be upon him) for nine years. Whatever work I did, the Prophet (peace and blessings be upon him) never said to me, "You did badly," or "You did wrong."
