Sunan Ibn Majah, Volume 2, Book 6, Hadith 1631 (DarusSalam) ⓘ

It was narrated that Anas said: “On the day when the Messenger of Allah entered Al-Madinah, everything was lit up, and on the day when he died, everything went dark, and no sooner had we dusted off our hands (after burying him) but we felt that our hearts had changed.”*

حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ الضُّبَعِيُّ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسٍ، قَالَ لَمَّا كَانَ الْيَوْمُ الَّذِي دَخَلَ فِيهِ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ الْمَدِينَةَ أَضَاءَ مِنْهَا كُلُّ شَىْءٍ فَلَمَّا كَانَ الْيَوْمُ الَّذِي مَاتَ فِيهِ أَظْلَمَ مِنْهَا كُلُّ شَىْءٍ ‏.‏ وَمَا نَفَضْنَا عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ الأَيْدِيَ حَتَّى أَنْكَرْنَا قُلُوبَنَا ‏.‏
