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 AND AMONG the folk of Moses there have been people who would guide [others] in the way of the truth and act justly in its light. 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 When they were told, "Settle down in this town, eat as you wish, seek forgiveness and enter the gate prostrating yourselves (in obedience to the Lord) and We will forgive you your sins and increase the reward of the righteous people, 161 the unjust among them changed the words which they were told to say (in the prayer). Therefore, We sent upon them torment from the sky for their wrong deeds. 162
