Dua of our prophet Mohamed after finish hearing the Azan, Amazing dua we all should recite it often.
O Allah, Lord of this perfect call and established prayer. Grant Muhammad salalho alaihi wa sallam the intercession and favor, and raise him to the honored station You have promised him, [verily You do not neglect promises].
• اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ، وَالصَّلاَةِ الْقَائِمَةِ، آتِ مُحَمَّداً الوَسِيلَةَ وَالْفَضِيلَةَ، وَابْعَثْهُ مَقَامَاً مَحمُوداً الَّذِي وَعَدْتَهُ، [إِنَّكَ لَا تُخْلِفُ الْمِيعَادَ]
