COMMENTARY on 39:5
A. Yusuf Ali:

Translation:
He created the heavens and the earth in true (proportions): 4247 He makes the Night overlap the Day, and the Day overlap the Night: He has subjected the sun and the moon (to His law): Each one follows a course for a time appointed. Is not He the Exalted in Power - He Who forgives 4248 again and again?
Commentary:

4247  Cf. 6:73, and n. 896.

4248  His Power is equalled by His Mercy. Who can there be like unto Him?

 

Muhammad Asad:

Translation:
He it is who has created the heavens and the earth in accordance with [an inner] truth. 5 He causes the night to flow into the day, and causes the day to flow into the night; and He has made the sun and the moon subservient [to His laws], each running its course for a term set [by Him]. 6 Is not He the Almighty, the All-Forgiving?
