Hisnul Muslim 25

Upon hearing the athan

اللَّهُـمَّ رَبَّ هَذِهِ الدَّعْـوَةِ التَّـامَّةِ، وَالصَّلَاةِ القَـائِمَة، آتِ مُحَـمَّداً الوَسِيـلَةَ وَالْفَضِـيلَةَ، وَابْعَـثْهُ مَقَـامـاً مَحْـمُوداً الَّذِي وَعَـدْتَهُ، إِنَّـكَ لَا تُـخْلِفُ المِيـعَادِ

Allaahumma Rabba haathihid-da 'watit-taammati wassalaatil-qaa'imati, 'aati Muhammadanil-waseelata walfadheelata, wab 'ath-hu maqaamam-mahmoodanil-lathee wa'adtahu, ['innaka laa tukhliful-mee'aad]

O Allah, Lord of this perfect call and established prayer. Grant Muhammad the intercession and favor, and raise him to the honored station You have promised him, verily You do not neglect promises.
