Translation:

108. Would ye question your Apostle as Moses was questioned of old? But whoever changeth from faith to unbelief hath strayed without doubt from the even way.

Notes (Tafseer)

108. Moses was contantly harassed with foolish, impertinent, or disingenuous questions by his own people. We must not follow that bad example. Questions should be asked only for real instruction.

109. "Even way": the Arabic word sawaa signifies smoothness as opposed to roughness: symmetry as opposed to want of plan; equality or proportion as opposed to want of design; rectitude as opposed to crookedness; a mean as opposed to extremes; and fitness for the object held in view as opposed to faultiness.
