I just want you to give me a simple explanation of the basic beliefs that a Muslim should hold regarding Allah and His Messenger (peace and blessings be upon him) and other matters. I sometimes get confused by the various different groups (Sunni, Shi’a, Salafi, Deobandi, Barelwi, etc) saying different things. I just need a simple yet comprehensive explanation, without detailed proofs, in regards to what is sufficient for a Muslim for salvation in the hereafter. Jazakum Allah.
