Some people ask why shia pray Namaze Zohr and Namaze Asr together, Namaze Maghrib and Namaze Isha together, while majority of Muslims are praying these Namazes separately and the name of every Namaz is different?
To reply to this question, we should put forward our principles in all our religious matters that we are following what exactly the Prophet Mohammed (S.A.W.) was doing. In our Namaz, how to pray Namaz, the timings of Namaz, and preparation for Namaz e.g. Wazu etc. and all things concerned with Namaz, we take it from the Prophet (S.A.W.) through the most authentic source which is Ahlul Bayt (A.S.) Not only Namaz but also all other Ahkaam (Rules). Every Hokm (Rule) in the Sharish we take from the Quran and from the Prophet (S.A.W).
