Translation:

39. "But those who reject Faith and belie Our Signs they shall be Companions of the Fire; they shall abide therein."

Notes (Tafseer)

57. But if the soul, in spite of the Oft-Returning Mercy of God, rejects the higher light and goes on sinning against that light, the inevitable consequence must be the spiritual Fire. It is not merely a fortuitous incident. As his rejection was deliberate and definite, so the consequences must be of an abiding character.
