Allah then exempted from these the believers, saying: (Save those who believe) in Muhammad (pbuh) and the Qur'an (and do good works) and do acts of obedience privately between themselves and their Lord, (for theirs is a reward) in Paradise (unfailing) undiminished and unblemished; it is also said this means: they will not be constantly reminded about the blessings bestowed upon them; and it is also said this means: their good deeds will not be decreased after they reach old age or after they die'.
