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 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, as nations; and We revealed to Musa when his people asked him for water: Strike the rock with your staff, so outnowed from it twelve springs; each tribe knew its drinking place; and We made the clouds to give shade over them and We sent to them manna and quails: Eat of the good things We have given you. And they did not do Us any harm, but they did injustice to their own souls. 160 And remember when they were commanded, “Reside in this township and eat whatever you wish in it, and say ‘Sins are forgiven’ and enter the gate prostrating – We will forgive you your sins; We shall soon bestow more upon the virtuous.” 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
