Verity the Messenger of Allah ﷺ said: There is for every apostle a (special) prayer with which he would pray. I wish I could reserve, my prayer for intercession of my Ummah on the Day of Resurrection.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِكُلِّ نَبِيٍّ دَعْوَةٌ يَدْعُوهَا فَأُرِيدُ أَنْ أَخْتَبِئَ دَعْوَتِي شَفَاعَةً لأُمَّتِي يَوْمَ الْقِيَامَةِ
