Radheetu billaahi Rabban, wa bi Muhammadin Rasoolan wabil-Islaami Deenan
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 Slave 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]

there is a typo in the image and text. it says “Muhammad is His SALVE” insted of “Muhammad is His slave”. jazaakallaahu khairan for this reminder.
