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 the people of Musa there is a community guiding others by the truth and judging thereby. 159 And We divided them into twelve tribes, forming them into communities. When his people asked Moses for water We directed him: 'Smite the rock with your rod.' Then twelve springs gushed forth from the rock and every people knew their drinking-places. And We caused thick clouds to provide them shade, and We sent down upon them manna and quails, saying: 'Eat of the clean things that We have provided you.' They wronged not Us, but it was themselves that they wronged. 160 And when it was said to them: Reside in this town and eat from it wherever you wish, and say, Put down from us our heavy burdens: and enter the gate making obeisance, We will forgive you your wrongs: We will give more to those who do good (to others). 161 But those among them who were bent on wrongdoing substituted another saying for that which they had been given: and so We let loose against them a plague from heaven in requital of all their evil doings. 162
