Translation:

191. And slay them wherever ye catch them and turn them out from where they have turned you out; for tumult and oppression are worse than slaughter; but fight them not at the Sacred Mosque unless they (first) fight you there; but if they fight you slay them. Such is the reward of those who suppress faith.

Notes (Tafseer)

205. This passage is illustrated by the events that happened at Hudaibiya in the sixth year of the Hijra, though it is not clear that it was revealed on that occasion. The Muslims were by this time a strong and influential community. Many of them were exiles from Mecca, where the Pagans had established an intolerant autocracy, persecuting Muslims, preventing them from visiting their homes, and even keeping them out by force from performing the Pilgrimage during the universally recognised period of truce. This was intolerance, oppression, and autocracy to the last degree, and the mere readiness of the Muslims to enforce their rights as Arab citizens resulted without bloodshed in an agreement which the Muslims faithfully observed. The Pagans, however, had no scruples in breaking faith, and it is unnecessary here to go into subsequent events.

206. Suppress faith: in the narrower as well as the larger sense. If they want forcibly to prevent you from exercising your sacred rites, they have declared war on your religion, and it would be cowardice to ignore the challenge or to fail in rooting out the tyranny.
