Surah Al-Ma'idah 5:28

لَئِنۢ بَسَطتَ إِلَىَّ يَدَكَ لِتَقْتُلَنِى مَآ أَنَا۠ بِبَاسِطٍ يَدِىَ إِلَيْكَ لِأَقْتُلَكَ ۖ إِنِّىٓ أَخَافُ ٱللَّهَ رَبَّ ٱلْعَـٰلَمِينَ

If you should raise your hand toward me to kill me - I shall not raise my hand toward you to kill you. Indeed, I fear Allāh, Lord of the worlds.
