Then he disputed with the polytheists over their worship of beings lacking the attributes of perfection. He said to his father:

“My father, why do you worship that which neither hears nor sees and cannot avail you at all?”

He said to his father and his people:

“What do you worship?”
“They replied, ‘We worship idols and remain devoted to them.’”
“He said, ‘Do they hear you when you call upon them, or benefit or harm you?’”

The passage continues:

“They are enemies to me, except the Lord of all worlds, who created me and guides me, who feeds me and gives me drink. And when I am ill, it is He who heals me, and who will cause me to die and then bring me to life.”

And so on to the end of the passage.

He also said:

“I have turned my face towards the One who created the heavens and the earth, upright in faith, and I am not one of the polytheists.”

And he said:

“I disavow whatever you worship, except the One who created me, for He will surely guide me.”
“He made this an enduring declaration among his descendants, so that they might return.”

Thus Abraham called people to the natural disposition: worshipping Allah alone, without any partner. This is Islam in its universal sense, affirming for Allah the attributes of words, and refuting those who worship beings bereft of them.

Having reproached them for worshipping beings that have no knowledge and neither hear nor see, he said:

“Our Lord, You know whatever we conceal and whatever we reveal. Nothing on earth or in heaven is hidden from Allah.”
“All praise is for Allah, who has granted me Ishmael and Isaac in my old age. Indeed, my Lord hears supplication.”
