Allâh's Messenger (ﷺ) said, "Whoever after listening to the Adhân says,

Allâhumma Rabba hadhihid-da ' watit-tâmmati was-şalâtil qâ'imati, Muḥammadanil-wasilata wal-fadilata, wab-' athhu maqâman maḥmûdanil-ladhi wa-' adtahu

[O Allah ! Lord of this perfect call (of not ascribing partners to You) and of the regular (prayer) which is going to be established ! Kindly give Muḥammad the right of intercession and superiority and send him (on the Day of Judgement) to the best and the highest place in Paradise which You promised him] ', then intercession for me will be permitted for him on the Day of Resurrection". [1:588-0.B.]
