Jabir reported God’s Messenger as saying:

If anyone says when he hears the summons, “O God, Lord of this perfect call and of the prayer which is established for all time, grant Muhammad the <i>wasila</i> and excellency, and raise him up in a praiseworthy position (Al-Qur’an; 17:79) which You have promised,” he will be assured of my intercession. Bukhari transmitted it.

وَعَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ قَالَ حِينَ يَسْمَعُ النِّدَاءَ اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ وَالصَّلَاةِ الْقَائِمَةِ آتِ مُحَمَّدًا الْوَسِيلَةَ وَالْفَضِيلَةَ وَابْعَثْهُ مَقَامًا مَحْمُودًا الَّذِي وَعَدْتَهُ حَلَّتْ لَهُ شَفَاعَتِي يَوْمَ الْقِيَامَة» . رَوَاهُ البُخَارِيّ
