Sahih Ibn Khuzaymah

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that a man came to the Prophet (peace and blessings of Allah be upon him) and informed him that he had kissed a woman, or touched her with his hand, or done something else. It was as if he was asking the Prophet (peace be upon him) about its expiation. He says that Allah Almighty then revealed this verse « وَأَقِمِ الصَّلَاةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِّنَ اللَّيْلِ ۚ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّيِّئَاتِ ۚ ذَٰلِكَ ذِكْرَىٰ لِلذَّاكِرِينَ » [ سورة هود ] "Establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds remove bad deeds. That is a reminder for those who remember." He says that the man asked, "Is this only for me?" The Prophet (peace be upon him) replied, "It is for every member of my Ummah who acts upon it." Imam Abu Bakr (may Allah have mercy on him) narrated, through the chain of Sulaiman Tamimi, a narration similar to the one mentioned above. In it, it is stated that he kissed a woman, and there are no words of doubt mentioned in it, nor are the words narrated that it was as if he was asking about its expiation.
