Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright. 158 And of Moses' folk there is a community who lead with truth and establish justice therewith. 159 And We divided them into twelve tribes, as separate groups; and when his people asked him for water, We revealed to Moosa, “Strike the rock with your staff”; so twelve springs gushed forth from it; each group recognised its drinking-place; and We made the clouds a canopy over them and sent down the Manna and the Salwa (birds) on them; “Eat of the good things we have provided you”; and they did not wrong Us in the least, but they used to wrong themselves. 160 And when it was said to them, 'Dwell in this township and eat of it wherever you will; and say, Unburdening; and enter in at the gate, prostrating; We will forgive you your transgressions, and increase the good-doers.' 161 So the unjust among them changed the words, contrary to what they had been commanded – consequently We sent down upon them a punishment from the sky – the recompense of their injustice. 162
