Ibn Mas'ud (May Allah be pleased with him) reported: A man kissed a woman. So he came to the Messenger of Allah (PBUH) and informed him about it. Then Allah revealed this Ayah: "And perform the Salat, between the two ends of the day and in some hours of the night. Verily, the good deeds efface the evil deeds (i.e., minor sins)." (11:114) The man asked the Messenger of Allah (PBUH) whether this applies to him only. The Messenger of Allah (PBUH) said, "It applies to all of my Ummah."
