Repeat What The Mu’adh-dhin Says, Except When He Says
يقول مثل ما يقول المؤذن إلا في (حي على الصلاة ، وحي على الفلاح) فيقول
Hayya ‘alas-Salāh (hasten to the prayer) and Hayya ‘alal-Falāh (hasten to salvation). Here you should say:
لا حول ولا قوة إلا بالله
Lā ḥawla wa lā quwwata ‘illā billāh.
There is no might and no power except by Allah.
وَأَنا أَشْـهَدُ أَنْ لا إِلـهَ إِلاّ اللهُ وَحْـدَهُ لا شَـريكَ لَـه ، وَأَنَّ محَمّـداً عَبْـدُهُ وَرَسـولُه، رَضيـتُ بِاللهِ رَبَّاً ، وَبِمُحَمَّـدٍ رَسـولاً وَبِالإِسْلامِ دينَـاً
Wa ‘anā ‘ash-hadu ‘an lā ‘ilāha ‘illallāhu waḥdahu lā sharīka lahu wa ‘anna Muḥammadan ‘abduhu wa rasūluhu, raḍītu billāhi rabban, wa bi Muḥammadin rasūlan wa bi ‘l-islāmi dīnan.
I bear witness that none has the right to be worshipped but Allah 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.1
