Prophet Shuaib (Shuaib) - Shuaib's Message

Allah the Almighty revealed the story of Shuaib : And to (the people of) Madyan (Madian) (We sent) their brother Shuaib. He said: "0 my people! Worship Allah, you have no other Ilah (God) but Him. Verily, a clear proof (sign) from your Lord has come unto you; so give full measure and full weight and wrong not men in their things, and do not mischief on the earth after it has been set in order, that will be better for you, if you are believers. And sit not on every road, threatening, and hindering from the Path of Allah those who believe in Him, and seeking to make it crooked. And remember when you were but few, and He multiplied you. And see what was the end of the Mufsideen (mischief-makers, corrupts, liars). And if there is a party of you who believes in that which I have been sent and a party who do not believe, so be patient until Allah judges between us, and He is the Best of judges."

The Disbelievers' Threat
The chiefs of those who were arrogant among his people said: "We shall certainly drive you out, 0 Shuaib and those who have believed with you from our town, or else you (all) shall return to our religion."
He said: "Even though we hate it! We should have invented a lie against Allah if we returned to your religion, after Allah has rescued us from it. And it is not for us to return to it unless Allah, our Lord, should will. Our Lord comprehends all things in His Knowledge. In Allah (Alone) we put our trust. Our Lord! Judge between us and our people in truth, for You are the Best of those Who give judgment."
The chiefs of those who disbelieved among his people said (to their people): "If you follow Shuaib, be sure then you will be the losers!" Surah 85-90
