Surah An-Nisa' (The Women), Verse 49

اَلَمْ تَرَ اِلَی الَّذِیْنَ یُزَكُّوْنَ اَنْفُسَهُمْ بَلِ اللّٰهُ یُزَكِّیْ مَنْ یَّشَآءُ وَلَا یُظْلَمُوْنَ فَتِیْلًا ۟

Alam tara ilal lazeena yuzakkoona anfusahum; balil laahu yuzakkee mai yashaaa'u wa laa yuzlamoona fateelaa

“Hast thou not turned Thy vision to those who claim sanctity for themselves? Nay-but Allah Doth sanctify whom He pleaseth. But never will they fail to receive justice in the least little thing.”

Quran 4:49 (Yusuf Ali Translation)
