Translation:

39. And fight them on until there is no more tumult or oppression and there prevail justice and faith in Allah altogether and everywhere; but if they cease verily Allah doth see all that they do.

Notes (Tafseer)

1207. Cf. ii. 193 and n.

1208. If they cease from fighting and from the persecution of truth, Allah judges then by their actions and their motives, and would not wish that they should be harassed with further hostility. But if they refuse all terms, the righteous have nothing to fear: Allah will help and protect them.
