Ask the Israelites how many a clear sign have We given them; and whoever changes the favor of Allah after it has come to him, then surely Allah is severe in requiting (evil).

And (make him) a messenger to the children of Israel: That I have come to you with a sign from your Lord, that I determine for you out of dust like the form of a bird, then I breathe into it and it becomes a bird with Allah's permission and I heal the blind and the leprous, and bring the dead to life with Allah's permission and I inform you of what you should eat and what you should store in your houses; most surely there is a sign in this for you, if you are believers.

And certainly We gave Musa nine clear signs; so ask the children of Israel. When he came to them, Firon said to him: Most surely I deem you, O Musa, to be a man deprived of reason.

So go you both to him and say: Surely we are two messengers of your Lord; therefore send the children of Israel with us and do not torment them! Indeed we have brought to you a communication from your Lord, and peace is on him who follows the guidance;
