Anas (may Allah be pleased with him) reports:
"Messenger of Allah ﷺ was sitting at the grave of his daughter (Sayyiditina Ummi Kulthum (may Allah be pleased with her)) and tears were flowing from his eyes. Messenger of Allah ﷺ said: 'That person should enter the grave who did not have sexual relations that (previous) night'. Abu Talhah (may Allah be pleased with him) replied: 'I did not'. At the request of Messenger of Allah ﷺ he entered her grave"

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ: أَخْبَرَنَا أَبُو عَامِرٍ، قَالَ: حَدَّثَنَا فُلَيْحٌ وَهُوَ ابْنُ سُلَيْمَانَ، عَنْ هِلالِ بْنِ عَلِيٍّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ: شَهِدْنَا ابْنَةً لِرَسُولِ اللهِ ﷺ، وَرَسُولُ اللهِ جَالِسٌ عَلَى الْقَبْرِ، فَرَأَيْتُ عَيْيَنْهِ تَدمَعَانِ، فَقَالَ: أَفِيكُمْ رَجُلٌ لَمْ يُقَارِفِ اللَّيْلَةَ؟، قَالَ أَبُو طَلْحَةَ: أَنَا، قَالَ: انْزِلْ فَنَزَلَ فِي قَبْرِهَا.
