Surah An-Nisa Verse 49 - English Translation by Muhammad Taqi Ud Din Al Hilali And Muhammad Muhsin Khan
Surah An-Nisaأَلَمۡ تَرَ إِلَى ٱلَّذِينَ يُزَكُّونَ أَنفُسَهُمۚ بَلِ ٱللَّهُ يُزَكِّي مَن يَشَآءُ وَلَا يُظۡلَمُونَ فَتِيلًا
Have you not seen those who claim sanctity for themselves. Nay - but Allah sanctifies whom He pleases, and they will not be dealt with injustice even equal to the extent of a Fatila (A scalish thread in the long slit of a date-stone)
