أَمَّنْ هَـٰذَا ٱلَّذِى يَرْزُقُكُمْ إِنْ أَمْسَكَ رِزْقَهُۥ ۚ بَل لَّجُّوا۟ فِى عُتُوٍّ وَنُفُورٍ Qur’an Al-Mulk (67:21)Amman hatha allathee yarzuqukum in amsaka rizqahu bal lajjoo fee AAutuwwin wanufoorin
"Sustenance" here, as elsewhere, (e.g., in xvi. 73, n. 2105), refers to all that is necessary to sustain and develop life in all its phases. Allah Most Gracious is the Source of all our Sustenance, and if we persist in looking to Vanities for our Sustenance, we are pursuing a mirage, and, if we examine the matter, we are only following obstinate unpulses of rebellion and impiety.
