(29:15) But We saved him and the companions of the ship, and We made it a sign for the worlds. (29:16) And [We sent] Abraham, when he said to his people, "Worship Allah and fear Him. That is best for you, if you should know. (29:17) You only worship, besides Allah, idols, and you produce a falsehood. Indeed, those you worship besides Allah do not possess for you [the power of] provision. So seek from Allah provision and worship Him and be grateful to Him. To Him you will be returned." (29:18) And if you [people] deny [the message] - already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification. (29:19) Have they not considered how Allah begins creation and then repeats it? Indeed that, for Allah, is easy. (29:20) Say, [O Muhammad], "Travel through the land and observe how He began creation. Then Allah will produce the final creation. Indeed Allah, over all things, is competent." (29:21) He punishes whom He wills and has mercy upon whom He wills, and to Him you will be returned.
