Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way (Holy Qur’an 16:125)
We will soon show them Our signs in the Universe and in their own souls, until it will become quite clear to them that it is the truth. Is it not sufficient as regards your Lord that He is a witness over all things? (Holy Qur'an 41:53)
