Have you not seen that all those who are in the heavens and the earth praise Allah, and the birds with their wings spread (also praise Him)? Each one has learnt its prayers and its words of praise; and Allah knows their deeds. 41 And unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 42 See you not that Allah drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain comes forth from between them. And He sends down from the sky hail (like) mountains, (or there are in the heaven mountains of hail from where He sends down hail), and strike therewith whom He will, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabari]. 43 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 Allah has created every moving (living) creature from water. Of them there are some that creep on their bellies, some that walk on two legs, and some that walk on four. Allah creates what He wills. Verily! Allah is Able to do all things. 45 Verily We have sent down revelations and explained them. Allah guideth whom He will unto a straight path. 46 They say, "We believe in Allah and in the messenger, and we obey": but even after that, some of them turn away: they are not (really) Believers. 47 When they are called to God and His Messenger that he may judge between them, lo, a party of them are swerving aside; 48 But if right had been with them they would have come unto him willingly. 49 Are their hearts sick? Do they have doubts or are they afraid that God and His Messenger may do injustice to them? In fact, they, themselves, are unjust. 50
