Hisn al-Muslim (Fortress of the Muslim) 23
يَقُولُ: ((وَأَنَا أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَنَّ مُحَمَّداً عَبْدُهُ وَرَسُولُهُ، رَضِيتُ بِاللَّهِ رَبَّاً، وَبِمُحَمَّدٍ رَسُولاً، وَبِالْإِسْلاَمِ دِينَاً)) ((يَقُولُ ذَلِكَ عَقِبَ تَشَهُّدِ الْمُؤَذِّنِ)).
Immediately following the declaration of faith called by the mu-aththin, one says:‘And I too bear witness that none has the right to be worshipped except Allah, alone, without partner, and that Muhammad is His salve and Messenger. I am pleased with Allah as a Lord, and Muhammad as a Messenger and Islam as a religion.’
