This dua is recited after hearing the adhan.
اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ، وَالصَّلَاةِ الْقَائِمَةِ، آتِ مُحَمَّداً الْوَسِيلَةَ وَالْفَضِيلَةَ، وَابْعَثْهُ مَقَاماً مَحْمُوداً الَّذِي وَعَدْتَهُ، إَنَّكَ لَا تُخْلِفُ الْمِيعَادَ
Allaahumma Rabba haathid – da’watit – taammati wassalaatil-qaa’imati, ‘aati Muhammadanil-waseelata walfadheelata, wab ‘ath-hu maqaamam-mahmoodanil-lathee wa’adtahu, ‘innaka laa tukhliful-mee’aad
