Mukhtasar Bukhari

Narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him): A man kissed a (non-mahram) woman, then he came to the Prophet (peace and blessings of Allah be upon him) and informed him about it. So Allah, the Most Great and Exalted, revealed this verse: "Establish prayer at the two ends of the day and in some hours of the night. Indeed, good deeds erase bad deeds." The man said, "O Messenger of Allah! Is this only for me?" The Prophet (peace and blessings of Allah be upon him) replied, "It is for my entire Ummah."
