20. And on them did Satan prove true his idea and they followed him all but a Party that believed.

Notes (Tafseer)

3820. Cf. xvii. 62. Satan out of arrogance had said, when he asked for respite from the Most High; "I will bring (Adam's) descendants under my sway, all but a few." This was now proved true on the Saba people. He had no power to force them. It was their own will that went wrong and put them into his power.
