(Ashoora) 42 : 19
اللَّهُ لَطِيفٌ بِعِبَادِهِ يَرْزُقُ مَنْ يَشَاءُ ۖ وَهُوَ الْقَوِيُّ الْعَزِيزُ
Allah is the knower of the innermost feeling of the Soul of His servants; He gives sustenance to whom He wishes, and He is the strong, the Exalted.
Since the Three-Time-Knower Allah knows even the innermost feeling of the soul, He decides to whom and when Adhikr (the Food, Cloth, and Sight of the human Soul) is to be given. This verse teaches that He is also capable of retaining Adhikr in whom He has given It. See explanation 4: 32; 6: 103-104; 25: 58, and 67: 14.
