Narrated Jabir bin `Abdullah: Allah’s Apostle said, “Whoever after listening to the Adhan says,
‘Allahumma Rabba hadhihi-d-da`watit-tammah, was-salatil qa’imah, ati Muhammadan al-wasilata wal-fadilah, wa b`ath-hu maqaman mahmudan-il-ladhi wa`adtahu’
[O Allah! Lord of this perfect call (perfect by not ascribing partners to You) and of the regular prayer which is going to be established, give Muhammad the right of intercession and illustriousness, and resurrect him to the best and the highest place in Paradise that You promised him (of)],
then my intercession for him will be allowed on the Day of Resurrection”.
