Anas b. Malik reported that Allah, the Exalted and Glorious, sent revelation to Messenger of Allah ﷺ just before his death in quick succession until he left for his heavenly home, and the day when he died, he received the revelation profusely. (Using translation from Muslim 3016)
أَنَّ اللهَ ﷻ تَابَعَ الْوَحْيَ عَلَى رَسُولِ اللهِ ﷺ قَبْلَ وَفَاتِهِ حَتَّى تُوُفِّيَ أَكْثَرَ مَا كَانَ الْوَحْيُ يَوْمَ تُوُفِّيَ رَسُولُ اللهِ ﷺ
