Say thou: O mankind! verily I am the apostle of Allah unto you all - of Him whose is the dominion of the heavens and the earth. No god is there but He; He giveth life and causeth to die. Believe then in Allah and His prophet, the unlettered prophet, who believeth in Allah and His words, and follow him that haply ye may be guided. 158 And among the people of Moses is a community which guides by truth and by it establishes justice. 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 Then those of them who did wrong changed the word that had been told them for another, whereupon We sent upon them a scourge from the heaven for they were wont to transgress. 162
