Amr b. Abu Sufyan reported:
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى ، أَخْبَرَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي يُونُسُ ، عَنِ ابْنِ شِهَابٍ ، أَنَّ عَمْرَو بْنَ أَبِي سُفْيَانَ بْنِ أَسِيدِ بْنِ جَارِيَةَ الثَّقَفِيَّ ، أَخْبَرَهُ أَنَّ أَبَا هُرَيْرَةَ قَالَ لِكَعْبِ الأَحْبَارِ إِنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم قَالَ " لِكُلِّ نَبِيٍّ دَعْوَةٌ يَدْعُوهَا فَأَنَا أُرِيدُ إِنْ شَاءَ اللَّهُ أَنْ أَخْتَبِئَ دَعْوَتِي شَفَاعَةً لأُمَّتِي يَوْمَ الْقِيَامَةِ " . فَقَالَ كَعْبٌ لأَبِي هُرَيْرَةَ أَنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ أَبُو هُرَيْرَةَ نَعَمْ .
Abu Huraira said to Ka'b al-Ahbar that the Messenger of Allah (ﷺ) had said: For every apostle there Is a (special) prayer by which he would pray (to his Lord). I, however, intend (if Allah so willed) that I would reserve my prayer for the intercession of my Ummah on the Day of Resurrection. Ka'b said to Abu Huraira: Did you hear this from the Messenger of Allah (ﷺ)? Abu Huraira said: Yes.
