عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رُقَيَّةَ رَضِيَ اللَّهُ عَنْهَا لَمَّا مَاتَتْ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”لَا يَدْخُلِ الْقَبْرَ رَجُلٌ قَارَفَ أَهْلَهُ“ فَلَمْ يَدْخُلْ عُثْمَانُ بْنُ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ الْقَبْرَ
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the daughter of the Prophet (peace and blessings be upon him), Sayyida Ruqayyah (may Allah be pleased with her), passed away, the Prophet (peace and blessings be upon him) said: "Whoever has had intercourse with his wife last night should not enter the grave." Thus, Sayyiduna Uthman ibn Affan (may Allah be pleased with him) did not enter the grave.
