Justice and reliance on Divine judgment

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.
