Translation for 4:93

وَمَن يَقۡتُلۡ مُؤۡمِنٗا مُّتَعَمِّدٗا فَجَزَآؤُهُۥ جَهَنَّمُ خَٰلِدٗا فِيهَا وَغَضِبَ ٱللَّهُ عَلَيۡهِ وَلَعَنَهُۥ وَأَعَدَّ لَهُۥ عَذَابًا عَظِيمٗا ٩٣
And whoever kills a believer intentionally, their reward will be Hell—where they will stay indefinitely.1 Allah will be displeased with them, condemn them, and will prepare for them a tremendous punishment.

 If a Muslim commits a major sin (such as intentional killing or adultery) and dies without repenting, they will be punished in Hell according to the severity or magnitude of the sin, then eventually be taken out of Hell. No Muslim will stay in Hell forever.
