The hudud (boundaries/limits) of Allah

وَمَن يَعْصِ ٱللَّهَ وَرَسُولَهُۥ وَيَتَعَدَّ حُدُودَهُۥ يُدْخِلْهُ نَارًا خَـٰلِدًا فِيهَا وَلَهُۥ عَذَابٌ مُّهِينٌ

And whoever disobeys Allāh and His Messenger and transgresses His limits - He will put him into the Fire to abide eternally therein, and he will have a humiliating punishment.
