An-Nisa 4:112

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

Waman yaksib khaṭīatan aw ith'man thumma yarmi bihi barīan faqadi iḥ'tamala buh'tānan wa-ith'man mubīnan

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.
