This is because Allah is the Protector of the believers while the unbelievers have no protector
Dr. Munir Munshey
Because the believers have Allah as their Patron, while the unbelievers have no patron
Dr. Kamal Omar
This is because Allah is Maula (Protector, Ally, Helper, Master) of those who have Believed and as those who are disbelievers — there is no Maula for them
That is because Allah is the Maula (Lord, Master, Helper, Protector, etc.) of those who believe, and the disbelievers have no Maula (lord, master, helper, protector, etc.)
That is (the truth of the matter)! Allah is the protector over the believers. But those who deny the knowledge of the reality have no protector!
