(And (bethink you of) the day when We raise in every nation) when We take from every group (a witness) a prophet (against them) testifying that he conveyed the message to them (of their own folk) a human being like them, (and We bring thee) O Muhammad (as a witness against these) against your people; it is also said that this means: a witness for your nation that they had accepted the message. (And We reveal the Scripture unto thee) and We send Gabriel to you with the Qur'an (as an exposition of all things) of the lawful and unlawful, the commands and prohibitions, (and a guidance) from error (and a mercy) preventing from chastisement (and good tidings for those who have surrendered (to Allah)) that they will have Paradise.
