۞ وَمَآ أُبَرِّئُ نَفْسِىٓ ۚ إِنَّ ٱلنَّفْسَ لَأَمَّارَةٌۢ بِٱلسُّوٓءِ إِلَّا مَا رَحِمَ رَبِّىٓ ۚ إِنَّ رَبِّى غَفُورٌۭ رَّحِيمٌۭ
I do not exculpate myself. Lo! the (human) soul enjoineth unto evil, save that whereon my Lord hath mercy. Lo! my Lord is Forgiving, Merciful.

Chapter: Whoever took his right or retaliation from somebody without submitting the case to the ruler
Narrated Abu Huraira:
That he heard Allah's Messenger (ﷺ) saying, "We (Muslims) are the last (to come) but (will be) the foremost (on the Day of Resurrection)." And added, "If someone is peeping (looking secretly) into your house without your permission, and you throw a stone at him and destroy his eyes, there will be no blame on you."
