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 among the people of Moses is a community which guides by truth and by it establishes justice. 159 We divided them into twelve tribes, each a nation. And when his people demanded drink, We revealed to Moses: 'Strike the rock with your staff' Thereupon twelve springs gushed from the rock and each tribe knew its drinking place. We caused the clouds to cast their shadow over them, and sent down for them manna and quails, saying: 'Eat of the good things We have provided for you' Indeed, they did Us no wrong, but they wronged themselves. 160 And recall what time it was said unto them: dwell in yonder town and eat plentifully therefrom anything ye list, and say: fergiveness, and enter the gate bowing; and We will forgive you your trespasses: anon We will increase unto the well-doers. 161 Then those of them who did wrong changed the word that had been told them for another, whereupon We sent upon them a scourge from the heaven for they were wont to transgress. 162
