Riyad as-Salihin, Book 1, Hadith 360 (In-Book) ⓘ

Anas bin Malik (May Allah be pleased with him) reported: After the death of Messenger of Allah, Abu Bakr (May Allah be pleased with him) said to 'Umar (May Allah be pleased with him) : "Let us visit Umm Aiman (May Allah be pleased with her) as Messenger of Allah used to visit her". As we came to her, she wept. They (Abu Bakr and 'Umar (May Allah be pleased with him) said to her, "What makes you weep? Do you not know that what Allah has in store for His 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 Messenger of Allah (in the Hereafter) is better than this world, but I weep because the Revelation has ceased to come". This moved both of them to tears and they began to weep along with her.[Muslim].

وعن أنس رضي الله عنه قال‏:‏ قال أبو بكر لعمر رضي الله عنهما بعد وفاة رسول الله صلى الله عليه وسلم‏:‏ انطلق بنا إلى أم أيمن رضي الله عنها نزورها كما كان رسول الله صلى الله عليه وسلم يزورهان فلما انتهيا إليها، بكت، فقالا لها، ما يبكيك أما تعلمين أن ما عند الله خير لرسول الله صلى الله عليه وسلم‏؟‏ فقالت‏:‏ إني لا أبكي إني لا أعلم أن ما عند الله تعالى خير لرسول الله صلى الله عليه وسلم ، ولكن أبكي أن الوحي قد انقطع من السماء، فهيجتهما على البكاء، فجعلا يبكيان معها‏.‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
