Protection of reputation and honor

وَمَن يَكْسِبْ خَطِيٓـَٔةً أَوْ إِثْمًا ثُمَّ يَرْمِ بِهِۦ بَرِيٓـًٔا فَقَدِ ٱحْتَمَلَ بُهْتَـٰنًا وَإِثْمًا مُّبِينًا

But whoever earns an offense or a sin and then blames it on an innocent [person] has taken upon himself a slander and manifest sin.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَكُونُوا۟ كَٱلَّذِينَ ءَاذَوْا۟ مُوسَىٰ فَبَرَّأَهُ ٱللَّهُ مِمَّا قَالُوا۟ ۚ وَكَانَ عِندَ ٱللَّهِ وَجِيهًا

O you who have believed, be not like those who abused Moses; then Allāh cleared him of what they said. And he, in the sight of Allāh, was distinguished.
