‘Abdallah b. Mas'ud told of a man coming to the Prophet and saying, “Messenger of God, I sported with a woman on the outskirts of Medina, and I got what I wanted from her short of having intercourse with her. Now here I am, so decide what you wish about me.” ‘Umar said to him, “God has concealed this about you. Would that you had kept it to yourself!” Ibn Mas'ud said that the Prophet gave no reply, so the man got up and went away. Then the Prophet sent a man after him to summon him, and he recited this verse to him. “And observe the prayer at the two ends of the day and the neighbouring parts of the night, for good deeds remove evil deeds. That is a reminder to those who remember (Al-Qur’an, 11:114).” One of the people asked, “Prophet of God, does this refer to him in particular?” He replied, “No, it refers to all men.” Muslim transmitted it.
