dua at the time of the Adhaan

Sa’d b. Abu Waqqas reported: The Messenger of Allah (may peace be upon him) said: If anyone says on hearing the Mu’adhdhin:

وَأَنا أَشْـهَدُ أَنْ لا إِلـهَ إِلاّ اللهُ وَحْـدَهُ لا شَـريكَ لَـه ، وَأَنَّ محَمّـداً عَبْـدُهُ وَرَسـولُه ، رَضيـتُ بِاللهِ رَبَّاً ، وَبِمُحَمَّـدٍ رَسـولاً وَبِالإِسْلامِ دينَـاً .

Wa ‘anaa ashhadu an laa ilaaha illal-laahu wahdahu laa shareeka lahu, wa ‘anna Muhammadan ‘abduhu wa Rasooluhu, radheetu billaahi Rabban, wa bi Muhammadin Rasoolan wabil-islami deenan.

‘I bear witness that none has the right to be worshipped but Allaah alone, Who has no partner, and that Muhammad is His salve and His Messenger. I am pleased with Allah as my Lord, with Muhammad as my Messenger and with Islam as my religion.’

his sins would be forgiven [1]
