The mother of Sayyiduna Uthman bin Abi al-As (may Allah be pleased with him) (may Allah be pleased with her) narrated: "I was present with Aminah when she gave birth to the Messenger of Allah (peace and blessings be upon him). When her labour pains began, I saw the stars hanging down so low that I began to say: They will fall upon me. Then, when she gave birth to him (peace and blessings be upon him), a light came out from her by which the house we were in and the courtyard were lit up, and I could see nothing but light."
