It was narrated that Ibn Abbas said: "There was a woman who used to pray behind the Messenger of Allah (ﷺ) who was beautiful, one of the most beautiful of people. Some of the people used to go to the front row to avoid seeing her, and some used to go to the back row so that when they bowed they could see her from beneath their armpits. Then Allah revealed the words: 'To Us are known those of you who hasten forward and those who lag behind."
