Dua on Hearing the Call to Prayer

اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ وَالصَّلَاةِ الْقَائِمَةِ آتِ مُحَمَّدَاً
 الْوَسِيلَةَ وَالْفَضِيلَةَ وَابْعَثْهُ مَقَامَاً مَحْمُودَاً الَّذِي وَعَدْتَهُ
O Allah, the Lord of this perfect call and of this established prayer, grant Muhammad (peace be upon him) the wasilah and honour and raise him to the praiseworthy position You have promised him.
(Bukhari)
