﴿أَلَمْ تَرَ إِلَى الَّذِينَ يُزَكُّونَ أَنْفُسَهُمْ ۚ بَلِ اللَّهُ يُزَكِّي مَنْ يَشَاءُ وَلَا يُظْلَمُونَ فَتِيلًا﴾
49. Have you not seen those (Jews and Christians)[5] who claim sanctity for themselves. Nay, but Allâh sanctifies whom He wills, and they will not be dealt with injustice even equal to the extent of a scalish thread in the long slit of a date-stone.
