We (once) sent Noah to his people, and he tarried among them a thousand years less fifty: but the Deluge overwhelmed them while they (persisted in) sin. 14 But We saved him and the companions of the ship, and We made it a sign for the worlds. 15 And Abraham, [too, was inspired by Us] when he said unto his people: "Worship God, and be conscious of Him: this is the best for you, if you but knew it! 16 You worship idols besides God and you create falsehood. Whatever you worship besides Him cannot provide you with anything for your sustenance. Seek your sustenance from the bounties of God. Worship Him. Give Him thanks. To Him you will all return." 17 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. 18 Do they not see how Allah originates the Creation, and then brings it back? That is an easy matter for Allah. 19 Say: Travel in the earth and see how He makes the first creation, then Allah creates the latter creation; surely Allah has power over all things. 20 He punishes whomever He wills and has mercy upon whomever He wills; and towards Him only you are to return. 21 You are not able to frustrate Him either in the earth or heaven, nor have you, other than Allah, a guardian or helper. 22
