اللَّهُ أَكْبَرُ، اللَّهُ أَكْبَرُ، اللَّهُ أَكْبَرُ، سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ، وَإِنَّا إِلَى رَبِّنَا لَمُنْقَلِبُونَ
Allahu Akbar, Allahu Akbar, Allahu Akbar. Subhanal-ladhi sakhkhara lana hadha wa ma kunna lahu muqrinin, wa inna ila Rabbina lamunqalibun
Allah is the Greatest, Allah is the Greatest, Allah is the Greatest. Glory be to Him Who has subjected this to us, and we could never have it (by our efforts). And to our Lord we shall return.
