The Prophet (ﷺ) will defer his supplication in order to intercede for his ummah
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدٍ، - وَهُوَ ابْنُ زِيَادٍ - قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لِكُلِّ نَبِيٍّ دَعْوَةٌ دَعَا بِهَا فِي أُمَّتِهِ فَاسْتُجِيبَ لَهُ وَإِنِّي أُرِيدُ إِنْ شَاءَ اللَّهُ أَنْ أُؤَخِّرَ دَعْوَتِي شَفَاعَةً لأُمَّتِي يَوْمَ الْقِيَامَةِ " .
Abu Huraira reported: The Messenger of Allah (ﷺ) said: There was for every apostle a prayer with which he prayed for his Ummah and it was granted to him; but I wish, if Allah so wills, to defer my prayer for the intercession of my Ummah on the Day of Resurrection.
