Abraham's Call to Monotheism

“How could I fear what you associate with Him, when you do not fear setting up partners with Allah, for which He has sent no authority? Which side is more deserving of security, if you only knew?”

6:81How should I fear that which ye set up beside Him, when ye fear not to set up beside Allah that for which He hath revealed unto you no warrant? Which of the two factions hath more right to safety? (Answer me that) if ye have knowledge.
