Answered by Ustadh Tabraze Azam
Question: Assalam alaikum,
Is it true that leaving the prayer makes a person a disbeliever?
No, that is not the position of the vast majority of legal scholars. Rather, the person who does not pray is a sinful believer, and not a disbeliever. Holding otherwise is a dangerous position, and it is not the way of Ahl al-Sunna. [see: Does Neglecting the Prayer Entail Disbelief?]
