﴿ وَمَن يَكْسِبْ خَطِيٓـَٔةً أَوْ إِثْمًۭا ثُمَّ يَرْمِ بِهِۦ بَرِيٓـًۭٔا فَقَدِ ٱحْتَمَلَ بُهْتَٰنًۭا وَإِثْمًۭا مُّبِينًۭا ﴾

“But he who commits a fault or a sin and then throws the blame therefore on an innocent person, burdens himself with the guilt of calumny and [yet another] flagrant sin.”

In the eighth verse (112), a general rule of conduct has been set forth. It stipulates that anyone who himself commits a crime, then goes on to put the blame on some innocent person (as in the episode cited above where the theft was committed by Banu Ubayriq themselves and they went on to put the blame on Sayyidna Labid or the Jew) has done something grave by levelling a false accusation of great magnitude against an innocent person plus an open sin weighing heavy on one's shoulders.
