Surah An-Nisa' (The Women), Verse 93

وَمَنْ یَّقْتُلْ مُؤْمِنًا مُّتَعَمِّدًا فَجَزَآؤُهٗ جَهَنَّمُ خَالِدًا فِیْهَا وَغَضِبَ اللّٰهُ عَلَیْهِ وَلَعَنَهٗ وَاَعَدَّ لَهٗ عَذَابًا عَظِیْمًا ۟

Wa mai yaqtul mu'minam muta'ammidan fajazaaa'uhoo Jahannamu khaalidan feehaa wa ghadibal laahu' alaihi wa la'anahoo wa a'adda lahoo 'azaaban 'azeemaa

“If a man kills a believer intentionally, his recompense is Hell, to abide therein (For ever): And the wrath and the curse of Allah are upon him, and a dreadful penalty is prepared for him.”

Quran 4:93 (Yusuf Ali Translation)
