Meaning of 'There is not one of you but will pass over it'

Q 1: What is the explanation of Allah’s saying (meanings of which are translated as): There is not one of you but will pass over it (Hell): this is with your Lord; a Decree which must be accomplished. Then We shall save those who used to fear Allâh

A: Allah (Exalted be He) explains to His servants that all people, whether pious or impious, shall pass over the Sirat (the bridge) that is set across Hellfire. (Part No. 4; Page No. 260) It is out of Divine Justice, Wisdom, Grace and Mercy that Allah has prescribed this passage and made it binding upon Himself. This constitutes a matter already decreed and inevitable. Allah (Exalted be He) then saves from Hellfire whoever has feared Him in worldly life and did the divinely ordained acts of obedience and avoided all the forbidden sinful acts and wrong deeds. As for the wrongdoers, they will be abandoned in Hellfire, crammed together, humbled to their knees, as a just recompense for denying and mocking the Signs of Allah (Exalted be He).
