Translation:

55. Then which of the gifts of thy Lord (O man) wilt thou dispute about?

Notes (Tafseer)

5122. With a slight modification this forms the refrain of the next Sura but one, the highly artistic Sura of Rahman. In S. liv. 15, 17 etc., there is a similar refrain in different words. Every gift and benefit you have is from Allah, and to save you from the just punishment of your sins, Allah at all times sends revelations and Messengers to warn you. Why not accept Allah's Grace instead of disputing about it?
