Different Sects - Same Quran

Question: do Shiates 'read' the same Quran as Sunnis? 

Answer: Yes, they do read the same arabic Quran, though they differ in some beliefs, which leads to them being different sects. It is important to bear in mind that all religions have sects in them. In fact, two of the world's great religions: Judaism and Christianity both read the same book: What the Christians refer to as the Old Testament are the books which were written before Jesus.
