It is narrated from Abdullah bin Amir bin Rabi’ah that Umm al-Mu’minin Sayyida Aisha Siddiqa (may Allah be pleased with her) used to relate that one night the Messenger of Allah (peace and blessings be upon him) could not sleep. She was lying beside the Messenger of Allah (peace and blessings be upon him), and she asked him: O Messenger of Allah! What is the matter? The Messenger of Allah (peace and blessings be upon him) replied: I wish that some righteous man from among my companions would guard me tonight. While I was still thinking about this, I heard the sound of weapons. The Messenger of Allah (peace and blessings be upon him) asked: Who is it? The newcomer said: O Messenger of Allah! I am Sa’d bin Malik; I have come to have the honor of guarding you. (After this, the Messenger of Allah, peace and blessings be upon him, was so at ease that) Sayyida (may Allah be pleased with her) says: After that, I heard the Messenger of Allah (peace and blessings be upon him) snoring as he slept.
