Messenger of Allah said: "Whoever says, when he hears the call: (Allahumma, rabba hadhihidda 'watit-tammati was Salatilqa'imah, ati Muhammadanil wasilata wal-Fadilata, wab'athhu Maqamun Mahmudan alladhi wa'adtahu) 'O Allah! Lord of this perfect call and established prayer, grant Muhammad Al-Wasilah and Al-Fadilah, and raise him to the praised station that you promised him' - then intercession on the Day of Resurrection is made lawful for him."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ قَالَ حِينَ يَسْمَعُ النِّدَاءَ اللَّهُمَّ رَبَّ هَذِهِ الدَّعْوَةِ التَّامَّةِ وَالصَّلاَةِ الْقَائِمَةِ آتِ مُحَمَّدًا الْوَسِيلَةَ وَالْفَضِيلَةَ وَابْعَثْهُ مَقَامًا مَحْمُودًا الَّذِي وَعَدْتَهُ إِلاَّ حَلَّتْ لَهُ الشَّفَاعَةُ يَوْمَ الْقِيَامَةِ
