Narrated Salamah bin Sakhr (RA): When the month of Ramadan came, I feared lest I would have intercourse with my wife. So, I vowed az-Zihar (the she was like my mother). Then, one night something of her was uncovered to me and I had intercourse with her. Allah's Messenger ( صلی اللہ علیہ وسلم ) afterwards said to me, "Set a slave free," and I replied, "I do not possess one (that I can free)." He said, "Then fast two consecutive months." I replied, "Have I fallen into that which I have fallen into except due to fasting!?" He said, "Feed sixty poor people with an 'Araq (basket) of dates." [Reported by Ahmad and al-Arba'a except an-Nasa'i. Ibn Khuzaimah and Ibn al-Jarud graded it Sahih (authentic)] .
