Prohibition of slander and false accusation (qadhf)

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.
