Let, then, the deniers of the truth have their will: let them have their will for a little while.

Therefore grant a delay to the Unbelievers: Give respite to them gently (for awhile).

So give a respite to the disbelievers. Deal thou gently with them for a while.

So grant the disbelievers a respite -- let them alone for a while.

So allow time for the disbelievers. Leave them awhile.
