Surah An-Nisa Verse 49 - English Translation by Shabbir Ahmed
Surah An-Nisaأَلَمۡ تَرَ إِلَى ٱلَّذِينَ يُزَكُّونَ أَنفُسَهُمۚ بَلِ ٱللَّهُ يُزَكِّي مَن يَشَآءُ وَلَا يُظۡلَمُونَ فَتِيلًا
Have you seen those who claim that they have purified their souls? Purification of "Self" i.e. development of the personality can only be achieved according to the Laws of Allah, by service to humanity and not through rituals or mysticism (2:177), (13:17). In the Court of Allah, men and women shall find full recompense for their doings without the least injustice
