Sexual intercourse with wife in Ramadan.

وَيُذْكَرُ عَنْ أَبِي هُرَيْرَةَ رَفَعَهُ: «مَنْ أَفْطَرَ يَوْمًا مِنْ رَمَضَانَ، مِنْ غَيْرِ عُذْرٍ وَلاَ مَرَضٍ لَمْ يَقْضِهِ صِيَامُ الدَّهْرِ، وَإِنْ صَامَهُ». وَبِهِ قَالَ ابْنُ مَسْعُودٍ. وَقَالَ سَعِيدُ بْنُ الْمُسَيَّبِ وَالشَّعْبِيُّ وَابْنُ جُبَيْرٍ وَإِبْرَاهِيمُ وَقَتَادَةُ وَحَمَّادٌ يَقْضِي يَوْمًا مَكَانَهُ.Narrated Abu Hurairah on the authority of the Prophet ﷺ, “Whoever did not observe Saum (fast) for one day of Ramadan without genuine excuse or a disease, then even if he observed Saum (fast) for a complete year, it would not compensate for that day.” The same is narrated by Ibn Mas‘ud. Sa‘id bin Al-Musaiyab, Ash-Sha‘bi, Ibn Jubair, Ibrahim, Qatada and Hammad said, “He should observe Saum (fast) one day in lieu of that missed day.”
