On the authority of Ibn Mas'ud: A man committed a forbidden kiss with a woman, so he came to the Prophet, peace and blessings be upon him, and asked him about its expiation. Then was revealed: {And establish prayer at the two ends of the day and at the approaches of the night. Indeed, good deeds remove evil deeds} [Hud: 114]. The man said: "Is this for me, O Messenger of Allah?" He said: "For you and for whoever acts upon it from my ummah."(1)

This is a hasan sahih hadith.

3376 - 'Abd ibn Humayd narrated to us, he said: Husayn ibn 'Ali al-Ju'fi narrated to us, from Za'idah, from 'Abd al-Malik ibn 'Umayr, from 'Abd al-Rahman ibn Abi Layla, from Mu'adh ibn Jabal, who said: A man came to the Prophet, peace and blessings be upon him, and said: "O Messenger of Allah, what do you think of a man who met a woman with no acquaintance between them—there is nothing a man does with his wife except that he did it with her, except that he did not have intercourse with her?" He said: Then Allah revealed: {And establish prayer at the two ends of the day and at the approaches of the night. Indeed, good deeds remove evil deeds. That is a reminder for those who remember} [Hud: 114]. So he commanded him to perform ablution and pray. Mu'adh said: I said: "O Messenger of Allah, is this specific to him, or general for the believers?" He said: "Rather, it is general for the believers."(2)

This hadith's chain of transmission is not continuous; 'Abd al-Rahman ibn Abi Layla did not hear from Mu'adh ibn Jabal, and Mu'adh ibn Jabal died during the caliphate of 'Umar.

--------------------------------------------
(1) Its chain is sahih, and its takhrij has preceded under number (3372).
(2) Sahih through other witnesses, and this chain is weak due to its discontinuity, for 'Abd al-Rahman ibn Abi Layla did not hear from Mu'adh, and there is disagreement concerning it regarding 'Abd al-Malik ibn 'Umayr. Ahmad also recorded it (22112), and see the rest of its takhrij therein.
