AR-RAD (THE THUNDER) : 39-43

13:39. Allah doth blot out or confirm what He pleaseth: with Him is the Mother of the Book.

13:40. Whether We shall show thee (within thy life-time) part of what we promised them or take to ourselves thy soul (before it is all accomplished),- thy duty is to make (the Message) reach them: it is our part to call them to account.
13:41. See they not that We gradually reduce the land (in their control) from its outlying borders? (Where) Allah commands, there is none to put back His Command: and He is swift in calling to account.

13:42. Those before them did (also) devise plots; but in all things the master-planning is Allah's He knoweth the doings of every soul: and soon will the Unbelievers know who gets home in the end.
13:43. The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book."
