﴿ أَمَّنْ هَٰذَا ٱلَّذِى يَرْزُقُكُمْ إِنْ أَمْسَكَ رِزْقَهُۥ ۚ بَل لَّجُّوا۟ فِى عُتُوٍّۢ وَنُفُورٍ ﴾

“Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]!”

Birds flying in the air, the emergence of man’s sustenance from the soil and similar events are most wonderful. If one gives serious consideration to such things, one will become caught up in the realisation of God. But man is so forgetful that he indulges in arrogance in a world in which the natural phenomena visible all around him ought to teach him the lesson of obedience to God.
