Translation:

91. No son did Allah beget nor is there any god along with Him: (if there were many gods) behold each god would have taken away what he had created and some would have lorded it over others! Glory to Allah (He is free) from the (sort of) things they attribute to Him!

Notes (Tafseer)

2931. Cf. xvii. 42. The multiplicity of gods is intellectually indefensible, considering the unity of Design and Purpose in His wonderful Universe.
