(As-Swaffaath) 37 : 113
وَبَارَكْنَا عَلَيْهِ وَعَلَىٰ إِسْحَاقَ ۚ وَمِنْ ذُرِّيَّتِهِمَا مُحْسِنٌ وَظَالِمٌ لِنَفْسِهِ مُبِينٌ
And We blessed upon him and Ishaque, and among both of their offspring there are Muhsins, and there are those who have done unjustly to their soul manifestly.
The Muhsin is the one who lives seeing the Lord under the Light of the Best Book, Adhikr, as explained in verse 37: 80. Those who have wronged themselves are the hypocritical leaders and their blind followers who hide and reject Adhikr, as explained in verse 35: 32. See explanation 2: 254; 9: 67-68.
