It was narrated that Maimunah the freed (female) slave of the Messenger of Allah (ﷺ), said:“The Prophet (ﷺ) was asked about a man who kissed his wife when they were both fasting. He said: ‘They have broken their fast.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ، عَنْ إِسْرَائِيلَ، عَنْ زَيْدِ بْنِ جُبَيْرٍ، عَنْ أَبِي يَزِيدَ الضِّنِّيِّ، عَنْ مَيْمُونَةَ، مَوْلاَةِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَتْ: سُئِلَ النَّبِيُّ ـ صلى الله عليه وسلم ـ عَنْ رَجُلٍ قَبَّلَ امْرَأَتَهُ وَهُمَا صَائِمَانِ قَالَ: " قَدْ أَفْطَرَا " .
