“Indeed My Lord is upon the Straight Path” (Surah Hud:56)
“Say: I am on clear proof from my Lord, but you deny [the truth]. I do not have what your are impatient for (i.e. the Punishment). The judgement is only for Allah, He declares the truth, and He is the best of judges.” (Surah al-An’am:57)
Allah, all praises and glory be to Him, is the One who judges between His servants on this life and the Hereafter with justice and fairness. He will not oppress anyone, even to the extent of the weight of an atom. No person will be recompensed in a way that is greater than the magnitude of their sin, each person will only be given what they deserve. Not a single person will be denied any of their rights, because Allah is Al-’Adl, The Just, and He is Just in His regulation and decree.
