Hadith: "I am not weeping because I do not know that what Allah holds is better for the Messenger of Allah (may Allah's peace and blessings be upon him), but I weep because the revelation from the sky has stopped." Her words moved them to tears and they began to weep along with her

عن أنس بن مالك رضي الله عنه قال: قَال أَبُو بَكر لِعُمَر رضي الله عنهما بَعْدَ وَفَاةِ رَسُول الله صلى الله عليه وسلم : انْطَلِق بِنَا إِلَى أُمِّ أَيمَنَ -رَضِي الله عنها- نَزُورُهَا كَمَا كَانَ رَسول الله صلى الله عليه وسلم يَزُورُها، فَلَمَّا انتَهَيَا إِلَيهَا، بَكَت، فَقَالاَ لَهَا: مَا يُبكِيك؟ أَمَا تَعْلَمِين أَنَّ ما عِنْد الله خَيرٌ لِرَسول الله صلى الله عليه وسلم ؟ فَقَالَت: مَا أَبْكِي أَنْ لاَ أَكُون أَعلَم أَنَّ مَا عِندَ الله تعالى خَيرٌ لِرَسُول الله صلى الله عليه وسلم ، وَلَكِن أَبكِي أَنَّ الوَحي قَدْ انْقَطَع مِنَ السَّمَاء؛ فَهَيَجَتْهُمَا عَلَى البُكَاء؛ فَجَعَلاَ يَبْكِيَان مَعَهَا.
[صحيح] - [رواه مسلم]

Anas ibn Mālik (may Allah be pleased with him) reported: After the Prophet's death, Abu Bakr said to ‘Umar (may Allah be pleased with both of them): "Let us visit Umm Ayman, just as the Messenger of Allah (may Allah's peace and blessings be upon him) used to visit her." When they came to her, she wept. They said to her: "What makes you weep? Do you not know that what is with Allah is better for the Messenger of Allah?" She said: "I am not weeping because of not knowing that what is with Allah is better for the Messenger of Allah, but I weep because the revelation from the sky has stopped." Her words moved them to tears and they began to weep along with her.
[Authentic hadith] - [Narrated by Muslim]

Explanation

The Companions (may Allah be pleased with them) were the most eager of people to follow the Messenger of Allah (may Allah’s peace and blessings be upon him) in every aspect. They would even walk in the same path that he used to walk in, sit in the same places he used to sit in and do everything they knew he used to do. This Hadīth is a proof of that, as Abu Bakr and ‘Umar visited a woman whom the Messenger of Allah (may Allah’s peace and blessings be upon him) used to visit. They visited her only because of this. When they arrived at her home, she began to weep. They said to her why are you weeping? Do you not know that what Allah, Glorified and Exalted be He, has prepared for His Messenger is better than this world? She replied: I do not weep because of that, but rather because the revelation has ceased. This is because when the Prophet (may Allah’s peace and blessings be upon him) passed away, the revelation stopped, as there is no revelation after him. That is why Allah perfected the Shariah before he passed away. Allah, the Almighty, says: {This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion} [Al-Mā‘idah: 3]. Upon hearing her words, Abu Bakr and ‘Umar started weeping as well because she reminded them of what they had forgotten.
