To the Madyan people1 We sent Shu'ayb,2 one of their own brethren: he said: “O my people! worship God. Ye have no other god but Him. Now hath come unto you a clear (Sign) from your Lord! Give just measure and weight, nor withhold from the people the things that are their due; and do no mischief on the earth after it has been set in order: that will be best for you, if ye have Faith.
