يَقُولُ: «اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ ، وَالصَّلاةِ القَائِمَةِ ، آتِ مُحَمَّداً الوَسِيْلَةَ وَالفَضِيْلَةَ ، وَابْعَثْهُ مَقَاماً مَحْمُوْداً الَّذِي وَعَدْتَهُ ، [إِنَّكَ لاَ تُخْلِفُ الْمِيعَادِ]».

Say: “O Allāh, Owner of this perfect call and Owner of this prayer to be performed, bestow upon Muḥammad al-Wasīlah and al-Faḍīlah and send him upon a praised platform which You have promised him. (Verily, You never fail in Your promise.)”
