Call to Prayers (Adhaan)

Bukhari :: Book 1 :: Volume 11 :: Hadith 588

Narrated Jabir bin 'Abdullah:

Allah's Apostle said, "Whoever after listening to the Adhan says, 'Allahumma Rabba hadhihi-d-da' watit-tammati was-salatil qa'imati, ati Muhammadan al-wasilata wal-fadilata, wab' athhu maqaman mahmudan-il-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 Muhammad the right of intercession and superiority and send him (on the Day of Judgment) 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").
