1 Question: Why do Shiites combine their prayers? Is it permissible to do so?
Answer: It is permissible to combine Zuhr and Asr prayers and to perform them separately as it is permissible in both manners. Performing the two prayers separately is better. It is narrated that the Holy Prophet of Islam (pbuh) offered his prayers in both combined as well separate manners. He combined his prayers without being in an urgent situation like war or storm.
