And We did not send any messenger except in the language of his people to state clearly for them, and Allah sends astray whom He wills and guides whom He wills. And He is the Exalted in Might, the Wise. And We certainly sent Moses with our signs, "Bring out your people from darkness into the light and remind them of the days of Allah." Indeed in that are signs for everyone patient and grateful. And, when Moses said to his people, "Remember the favor of Allah upon you when He saved you from the people of Pharaoh, who were afflicting you with the worst torment and were slaughtering your sons and keeping your females alive. And in that was a great trial from your Lord.
THE QUR'AN, Ibraheem 14:4-6
