Is it permissible for Allah Almighty to admit the righteous to Hellfire and admit the disobedient to Paradise?

Allah, glory be to Him, has negated from Himself that He punishes the obedient and the righteous. He has forbidden injustice upon Himself and made it incumbent upon Himself to reward the obedient. The Almighty has informed us of His perfect self-sufficiency, the vastness of His forbearance, His mercy, and His benevolence. Indeed, He does not benefit from punishing the disobedient, nor does He find satisfaction in their torment. Rather, the disobedient harms only himself. It is from the sayings of the predecessors that Allah does not punish His prophets or those who obey Him, nor does He reward a disobedient person for their disobedience. Thus, everything that emanates from Him, glory be to Him, is wisdom and justice. Every blessing from Him is a grace, and every affliction from Him is justice. He does not punish a servant except for their sin. It has been reported in the Sunnah that "IF ALLAH WERE TO PUNISH THE INHABITANTS OF HIS HEAVENS AND THE INHABITANTS OF HIS EARTH, HE WOULD PUNISH THEM, AND HE WOULD NOT BE UNJUST TO THEM." This is true because the obedience of a servant does not equate to even one of Allah's blessings upon them. The remaining blessings upon them still necessitate gratitude. So, if He were to punish them for not being grateful for those blessings, He would not be unjust to them. For this reason, a servant's entry into Paradise is by Allah's mercy and generosity. It is important to note that the word "حضرت" (Hadrat) is not used in reference to Allah the Almighty.
