Riyad as-Salihin 1039

The Messenger of Allah (ﷺ) said, "He who says upon hearing the Adhan: 'Allahumma Rabba hadhihid-da'wati-ttammati, was-salatil-qa'imati, ati Muhammadanil-wasilata wal-fadhilata, wab'athu maqaman mahmuda nilladhi wa 'adtahu [O Allah, Rubb of this perfect call (Da'wah) and of the established prayer (As-Salat), grant Muhammad the Wasilah and superiority, and raise him up to a praiseworthy position which You have promised him]', it becomes incumbent upon me to intercede for him on the Day of Resurrection."[Al- Bukhari].
