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 Yet among the people of Moses there was a nation who preached the truth and acted justly. 159 And We cut them up into twelve tribes as communities. And We revealed unto Musa, when his people asked him for drink: Smite the rock with thy rod. Then gushed forth therefrom twelve springs: every people already knew their drinking-places. And We shaded them with thick clouds, and We sent down upon them the manna and the quails, saying: eat of the clean things wherewith We have provided you. And they wronged not Us, but themselves they were wont to wrong. 160 And remember when they were commanded, “Reside in this township and eat whatever you wish in it, and say ‘Sins are forgiven’ and enter the gate prostrating – We will forgive you your sins; We shall soon bestow more upon the virtuous.” 161 The wicked among them changed and perverted the word We had spoken to a word unpronounced; so We sent from heaven retribution on them for all their wickedness. 162
