4:49
أَلَمۡ تَرَ إِلَى ٱلَّذِینَ یُزَكُّونَ أَنفُسَهُمۚ بَلِ ٱللَّهُ یُزَكِّی مَن یَشَاۤءُ وَلَا یُظۡلَمُونَ فَتِیلًا
Hast thou not seen those who praise themselves for purity? Nay, Allah purifieth whom He will, and they will not be wronged even the hair upon a date-stone.
— Mohammed Marmaduke William Pickthall
Alam tara ilal lazeena yuzakkoona anfusahum; balil laahu yuzakkee mai yashaaa'u wa laa yuzlamoona fateelaa
