Sahih al-Bukhari 7474

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "For every Prophet there is one invocation which is definitely fulfilled by Allah, and I wish, if Allah will, to keep my that (special) invocation as to be the intercession for my followers on the Day of Resurrection."

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لِكُلِّ نَبِيٍّ دَعْوَةٌ، فَأُرِيدُ إِنْ شَاءَ اللَّهُ أَنْ أَخْتَبِيَ دَعْوَتِي شَفَاعَةً لأُمَّتِي يَوْمَ الْقِيَامَةِ ‏"‏‏.‏
