The Holy Quran 4:112 — Surah An-Nisa
Arabic text
وَمَن يَكْسِبْ خَطِيٓـَٔةً أَوْ إِثْمًا ثُمَّ يَرْمِ بِهِۦ بَرِيٓـًٔا فَقَدِ ٱحْتَمَلَ بُهْتَـٰنًا وَإِثْمًا مُّبِينًا
Translation
Whoever commits a minor sin (a mistake) or a major sin and then casts the blame on (accuses) an innocent person, he has indeed burdened himself with a great slander and clear sin (for which he will suffer terrible punishment).
Tafsir (excerpt) — Tafsir Usmani

So it became clear that by stealing himself and laying the accusation on the Jew [the thief] only increased his burden, and gained not the slightest benefit.
