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 Among the people of Moses' there was a party who guided others in the way of the truth and established justice in its light. 159 And We divided them into twelve tribes, [or] communities. And when his people asked Moses for water, We inspired him, "Strike the rock with thy staff!" - whereupon twelve springs gushed forth from it, so that all the people knew whence to drink. And We caused the clouds to comfort them with their shade, and We sent down unto them manna and quails, [saying:] "Partake of the good things which We have provided for you as sustenance." And [by all their sinning] they did no harm unto Us - but [only] against their own selves did they sin. 160 When it was said to them: 'Dwell in this village, and eat of whatever you please; and say, "Unburdening" and enter the gate prostrating, We will forgive you your sins and increase the gooddoers' 161 But those who were unjust among them changed it for a saying other than that which had been spoken to them; so We sent upon them a pestilence from heaven because they were unjust. 162
