4:49
اَلَمْ تَرَ اِلَى الَّذٖینَ یُزَكُّونَ اَنْفُسَهُمْؕ بَلِ اللّٰهُ یُزَكّٖی مَنْ یَشَٓاءُ وَلَا یُظْلَمُونَ فَتٖیلًا
Alam tara ila allatheena yuzakkoona anfusahum bali Allahu yuzakkee man yashao wala yuthlamoona fateelan
Translations
Have you not seen those who claim themselves to be pure? Rather, Allah purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed]
Saheeh International
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
Marmaduke Pickthall
