Sahih Muslim Book - 43, Hadith - 5973

وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ ، حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ ، عَنِ ابْنِ خُثَيْمٍ ، عَنْ عَبْدِ اللهِ بْنِ عُبَيْدِ اللهِ بْنِ أَبِي مُلَيْكَةَ ، أَنَّهُ سَمِعَ عَائِشَةَ ، تَقُولُ: سَمِعْتُ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: وَهُوَ بَيْنَ ظَهْرَانَيْ أَصْحَابِهِ إِنِّي عَلَى الْحَوْضِ أَنْتَظِرُ مَنْ يَرِدُ عَلَيَّ مِنْكُمْ ، فَوَاللَّهِ لَيُقْتَطَعَنَّ دُونِي رِجَالٌ ، فَلأَقُولَنَّ: أَيْ رَبِّ مِنِّي وَمِنْ أُمَّتِي ، فَيَقُولُ: إِنَّكَ لاَ تَدْرِي مَا عَمِلُوا بَعْدَكَ ، مَا زَالُوا يَرْجِعُونَ عَلَى أَعْقَابِهِمْ.

‘Aishah said: “I heard the Messenger of Allah (s.a.w) say when he was among his Companions: ‘I will be at the Cistern and I will see those of you who come towards me. By Allah, some men will be prevented from reaching me, and I will say: “O Lord, they belong to me and my Ummah.” He will say: “You do not know what they did after you were gone. They kept turning back on their heels.”’
