Say: 'O mankind, I am the Messenger of God to you all, of Him to whom belongs the kingdom of the heavens and of the earth. There is no god but He. He gives life, and makes to die. Believe then in God, and in His Messenger, the Prophet of the common folk, who believes in God and His words, and follow him; haply so you will be guided.' 158 Yet there is a group among the people of Moses who guide with truth and act justly in accordance with it. 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 And when it was said unto them: Dwell in this township and eat therefrom whence ye will, and say "Repentance," and enter the gate prostrate; We shall forgive you your sins; We shall increase (reward) for the right-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
