Nizari Ismailis recite the Ismaili Holy Du’a (called Du’a) instead of the Muslim prayer (called salāt in Arabic and namaz in Persian and Urdu). In Urdu-speaking countries, Ismailis insist that since the word namaz does not appear anywhere in the Quran, the namaz which is recited by the Muslims is never commanded by the Quran and that the Ismailis are free to call it Du’a since it is one of the meanings of the Arabic word salāt.
Beyond just the word, the Du’a offered by the Nizari Ismailis is not anything like the Muslim salāt which the Prophet (pbuh) used to offer and which Muslims to-date have learned and practised. Not only did the Prophet (pbuh) offered the Muslim salāt, he also instructed us:
Pray as you have seen me praying.
Other than being different than the Muslim salāt, a deeper inspection of this Du’a reveals many aspects of Ismailis’ own version of Trinity. Daily recitation of this Holy Du’a subliminally minimizes the difference between Allah (swt), Ali (ra) and Aga Khan since the Ismaili worshiper invokes all three during his prayer thinking that he is invoking a single deity.
