They said: You are nothing but mortals like us; you wish to turn us away from what our fathers used to worship; bring us therefore some clear authority.

And your Lord says: Call upon Me, I will answer you; surely those who are too proud for My service shall soon enter hell abased.

Say: I am forbidden to serve those whom you call upon besides Allah when clear arguments have come to me from my Lord, and I am commanded that I should submit to the Lord of the worlds.

And that when the servant of Allah stood up calling upon Him, they wellnigh crowded him (to death).
