Sahih al-Bukhari, Hadith 4982 ⓘ
Narrated Anas bin Malik: Allah sent down His Divine Inspiration to His Apostle continuously and abundantly during the period preceding his death till He took him unto Him. That was the period of the greatest part of revelation; and Allah's Messenger died after that.
حَدَّثَنَا عَمْرُو بْنُ مُحَمَّدٍ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبِي، عَنْ صَالِحِ بْنِ كَيْسَانَ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي أَنَسُ بْنُ مَالِكٍ ـ رضى الله عنه ـ أَنَّ اللَّهَ، تَعَالَى تَابَعَ عَلَى رَسُولِهِ صلى الله عليه وسلم قَبْلَ وَفَاتِهِ حَتَّى تَوَفَّاهُ أَكْثَرَ مَا كَانَ الْوَحْىُ، ثُمَّ تُوُفِّيَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَعْدُ.
