The Holy Quran 4:49 — Surah An-Nisa

Arabic text

أَلَمْ تَرَ إِلَى ٱلَّذِينَ يُزَكُّونَ أَنفُسَهُم ۚ بَلِ ٱللَّهُ يُزَكِّى مَن يَشَآءُ وَلَا يُظْلَمُونَ فَتِيلًا

Translation

Have you not seen those who proclaim (consider) their purity (who praise their piety)? Allaah purifies whoever He wills and does not oppress even (to the extent of) the string of a date seed (the fine thread found in the slit of a date seed).

Tafsir (excerpt) — Tafsir Usmani

The boasting of the Jews: that is, the Jews, despite so many vices, still call themselves pure, clean and holy, to the point that they declare themselves the sons of Allah and His beloved ones, which is utter nonsense. Rather, Almighty Allah makes pure and holy whomever He wills; nothing can come of what the Jews say.
