(Annisa) 4 : 111
وَمَنْ يَكْسِبْ إِثْمًا فَإِنَّمَا يَكْسِبُهُ عَلَىٰ نَفْسِهِ ۚ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا
And whoever earns a sin, then indeed he is earning against his soul, and Allah is the All-Knowing, the Wise.
By teaching Adhikr at the creation of mankind itself, the Lord has become the Impartial as told in verses 55: 1-4. See explanation 2: 121, 286; 4: 100 and 6: 104.
