Do you not see that Allah is exalted by whomever is within the heavens and the earth and [by] the birds with wings spread [in flight]? Each [of them] has known his [means of] prayer and exalting [Him], and Allah is Knowing of what they do. 41 To God belongs the kingdom of the heavens and the earth, and to Him do all things return. 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 [living] creature from water. And of them are those that move on their bellies, and of them are those that walk on two legs, and of them are those that walk on four. Allah creates what He wills. Indeed, Allah is over all things competent. 45 We have sent down revelations clearly showing the truth. God guides whom He wills to the straight path. 46 They say: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those are not believers. 47 and when they are called to God and His Messenger so that he may judge between them, some of them turn away. 48 But if the truth happens to be to their liking, they are quite willing to accept it! 49 What, is there sickness in their hearts, or are they in doubt, or do they fear that God may be unjust towards them and His Messenger? Nay, but those -- they are the evildoers. 50
