Al-Mukhtasar
وَمَن يَكْسِبْ خَطِيٓـَٔةً أَوْ إِثْمًا ثُمَّ يَرْمِ بِهِۦ بَرِيٓـًٔا فَقَدِ ٱحْتَمَلَ بُهْتَـٰنًا وَإِثْمًا مُّبِينًا ﴿١١٢﴾
If a person does a wrong action unintentionally or a sin intentionally and then accuses an innocent person of the same, they have taken on themselves a serious lie and a clear sin by acting in that manner.
