Verily the Messenger of Allah ﷺ said: There is for every apostle a prayer with which he prays (to Allah) for his Ummah. I have reserved my prayer for the intercession of my Ummah on the Day of Resurrection.
أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ لِكُلِّ نَبِيٍّ دَعْوَةٌ دَعَاهَا لأُمَّتِهِ وَإِنِّي اخْتَبَأْتُ دَعْوَتِي شَفَاعَةً لأُمَّتِي يَوْمَ الْقِيَامَةِ
