It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) was praying at night, and a woman was also performing prayer with him. When he noticed her, he said: "If you wish, you may lie down." She said: "I am still energetic." The Prophet (peace and blessings of Allah be upon him) said: "You are not like me; the coolness of my eyes is in the prayer."
