النساۤء — An-Nisa' Ayat 112

وَمَنْ يَّكْسِبْ خَطِيْۤـَٔةً اَوْ اِثْمًا ثُمَّ يَرْمِ بِهٖ بَرِيْۤـًٔا فَقَدِ احْتَمَلَ بُهْتَانًا وَّاِثْمًا مُّبِيْنًا ࣖ

Wa may yaksib khaṭī'atan au iṡman ṡumma yarmi bihī barī'an fa qadiḥtamala buhtānaw wa iṡmam mubīnā(n).

"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."
