Say: 'O mankind, I am the Messenger of Allah to you all. His is the kingdom in the heavens and the earth. There is no god except He. He revives and causes to die. Therefore, believe in Allah and His Messenger, the Unlettered Prophet, who believes in Allah and His Words. Follow him in order that you are guided.' 158 Yet among the people of Moses there was a nation who preached the truth and acted justly. 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 they were told, "Settle down in the town and eat wherever you wish in it, and pray for forgiveness and enter the gate in humility: We shall forgive you your sins and shall bestow further favours upon those who do good," 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
