Hellfire is the punishment for violating the rights of others

The Messenger of Allah ﷺ said: “Whoever takes away the right of a Muslim person by his (false) oath, Allah has made the Fire obligatory for him and has forbidden Paradise to him.” A man said to him: “Even if it is something insignificant, O Messenger of Allah?” He said: “Even if it is a twig from an arāk tree.”

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «مَنِ اقْتَطَعَ حَقَّ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ فَقَدْ أَوْجَبَ اللَّهُ لَهُ النَّارَ وَحَرَّمَ عَلَيْهِ الْجَنَّةَ»، فَقَالَ لَهُ رَجُلٌ: وَإِنْ كَانَ شَيْئًا يَسِيرًا يَا رَسُولَ اللَّهِ؟ قَالَ: «وَإِنْ قَضِيبًا مِنْ أَرَاكٍ».
