It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came to us while we were children. He (peace be upon him) greeted us with salam and sent me for some task, and he sat down on the way and waited for me until I returned. Sayyiduna Anas (may Allah be pleased with him) says that I was late in going to (my mother) Sayyida Umm Sulaym (may Allah be pleased with her), so she asked: Why were you late? I said: The Prophet (peace and blessings be upon him) had sent me for a task. She asked: For what task did he send you? I said: It was a confidential matter. She said: Then safeguard the secret of the Messenger of Allah (peace and blessings be upon him).
