Say: "O men, I am verily the apostle of God to you all. His whose kingdom extends over the heavens and the earth. There is no god but He, the giver of life and death. So believe in God and the messenger, the gentile Prophet, sent by Him, who believes in God and His messages. Obey him; you may haply be guided aright." 158 Of the people of Moses there is a nation who guide by the truth, and by it act with 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 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 the transgressors among them substituted something else for the word they had been given. So We sent them a punishment from heaven for their wrongdoing. 162
