"The Messenger of Allah said:

"'Whoever says when he hears the call to the prayer (Adhan):

اللّهُـمَّ رَبَّ هَذِهِ الدّعْـوَةِ التّـامَّة وَالصّلاةِ القَـائِمَة آتِ محَـمَّداً الوَسيـلةَ وَالْفَضـيلَة وَابْعَـثْه مَقـامـاً مَحـموداً الَّذي وَعَـدْتَه إِنَّـكَ لا تُـخْلِفُ الميـعاد.

Allahumma rabba hathihid-daAAwatit-tammah, wassalatil-qa-imah ati Muhammadan alwaseelata wal-fadeelah, wabAAath-hu maqaman mahmoodan allathee waAAadtah, innaka la tukhliful-meeAAad.

(O Allah, Lord of this perfect call and the prayer to be offered, grant Muhammad the privilege (of intercession) and also the eminence, and resurrect him to the praised position that You have promised)," Verily, You never fail in Your promise

my intercession for him will be permitted on the Day of Resurrection.'"

(Sunan Ibn Majah, Book 3, Hadith 722)
