People will be punished according to their sins
Samurah bin Jundub (radi Allahu anhu) reported that the Prophet of Allah (sal Allahu alaihi wa sallam) said, “Among the people of Hell are there those who will be emersed in fire to their ankels, some to their knees, some to their waists, and some to their throats.”
This Hadith tells us that the inhabitants of Hell will be classified in to different categories and they will suffer torments according to their misdeeds. A similar classification will also be made with the inhabitants of Jannah and they will enjoy different kinds of luxuries according to their merits.
And Allah Knows Best!
