Say [O Muhammad]: "O mankind! Verily, I am an apostle of God to all of you, [sent by Him] unto whom the dominion over the heavens and the earth belongs! There is no deity save Him; He [alone] grants life and deals death!" Believe, then, in God and His Apostle - the unlettered Prophet who believes in God and His words - and follow him, so that you might find guidance! 158 And of Musa's people was a party who guided (people) with the truth, and thereby did they do justice. 159 And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves. 160 And when it was said to them: "Live in this land and eat of its produce wheresoever you like, and ask for remission of your sins, but pass through the gates with submission (and not pride), We shall forgive your trespasses, and give to those who are righteous abundance," 161 Then the wrong-doers among them substituted another word in place of the one told them. So We sent upon them a scourge from the heaven as a punishment for their Wrong-doing. 162
