You are now the best people brought forth for (the guidance and reform of) mankind. You enjoin what is right and forbid what is wrong and believe in Allah. Had the People of the Book believed it were better for them. Some of them are believers but most of them are transgressors. (Al e Imran:110)
And it is thus that We appointed you to be the community of the middle way so that you might be witnesses to all mankind and the Messenger might be a witness to you. We appointed the direction which you formerly observed so that We might distinguish those who follow the Messenger from those who turn on their heels. For it was indeed burdensome except for those whom Allah guided. And Allah will never leave your faith to waste. Allah is full of gentleness and mercy to mankind. (Al Baqarah:143)
