Sahih Muslim , Hadith 2454 ⓘ
Anas reported that after the death of Allah's Messenger Abu Bakr said to 'Umar: Let us visit Umm Aiman as Allah's Messenger used to visit her. As we came to her, she wept. They (Abu Bakr and Umar) said to her: What makes you weep? What is in store (in the next world) for Allah's-Messenger is better than (this worldly life). She said: I weep not because I am ignorant of the fact that what is in store for Allah's Messenger (in the next world) is better than (this world), but I weep because the revelation which came from the Heaven has ceased to come. This moved both of them to tears and they began to weep along with her.
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، أَخْبَرَنِي عَمْرُو بْنُ عَاصِمٍ الْكِلاَبِيُّ، حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ قَالَ أَبُو بَكْرٍ رضى الله عنه بَعْدَ وَفَاةِ رَسُولِ اللَّهِ صلى الله عليه وسلم لِعُمَرَ انْطَلِقْ بِنَا إِلَى أُمِّ أَيْمَنَ نَزُورُهَا كَمَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَزُورُهَا . فَلَمَّا انْتَهَيْنَا إِلَيْهَا بَكَتْ فَقَالاَ لَهَا مَا يُبْكِيكِ مَا عِنْدَ اللَّهِ خَيْرٌ لِرَسُولِهِ صلى الله عليه وسلم . فَقَالَتْ مَا أَبْكِي أَنْ لاَ أَكُونَ أَعْلَمُ أَنَّ مَا عِنْدَ اللَّهِ خَيْرٌ لِرَسُولِهِ صلى الله عليه وسلم وَلَكِنْ أَبْكِي أَنَّ الْوَحْىَ قَدِ انْقَطَعَ مِنَ السَّمَاءِ . فَهَيَّجَتْهُمَا عَلَى الْبُكَاءِ فَجَعَلاَ يَبْكِيَانِ مَعَهَا .
