Salam alaikum. One of the points in which shias differed with us, is issue of islam of prophets parents.

In accordance to Quran, father of Ibrahim (alaihi salam) wasn’t believer.

Allah Taala said:

[Yusufali 6:74] Lo! Abraham said to his father Azar: “Takest thou idols for gods? For I see thee and thy people in manifest error.”

[Yusufali 9:114] And Abraham prayed for his father’s forgiveness only because of a promise he had made to him. But when it became clear to him that he was an enemy to Allah, he dissociated himself from him: for Abraham was most tender-hearted, forbearing.

[Yusufali 43:26] Behold! Abraham said to his father and his people: “I do indeed clear myself of what ye worship:

[Yusufali 19:41] (Also mention in the Book (the story of) Abraham: He was a man of Truth, a prophet.
[Yusufali 19:42] Behold, he said to his father: “O my father! why worship that which heareth not and seeth not, and can profit thee nothing?
[Yusufali 19:43] “O my father! to me hath come knowledge which hath not reached thee: so follow me: I will guide thee to a way that is even and straight.
[Yusufali 19:44] “O my father! serve not Satan: for Satan is a rebel against (Allah) Most Gracious.
[Yusufali 19:45] “O my father! I fear lest a Penalty afflict thee from (Allah) Most Gracious, so that thou become to Satan a friend.”
[Yusufali 19:46] (The father) replied: “Dost thou hate my gods, O Abraham? If thou forbear not, I will indeed stone thee: Now get away from me for a good long while!”
[Yusufali 19:47] Abraham said: “Peace be on thee: I will pray to my Lord for thy forgiveness: for He is to me Most Gracious.

All praise is to Allah One and Only, His book is very clear, father of noble prophet Ibrahim (alaihi salam) was disbeliever and polytheist.

When shias and other miquided sects are becoming speechless due to lack of proofs for their point of view, they starting twisting and playing with words.

They said:  Truly in verse used word “father”, but in reality that was his uncle.

We can see in verse that name of Ibrahim’s father was Azar. Let us go back to most authentic and most import book of hadeth for shias.

Kulayni in his “Kafi” (8/366-367/#558) narrated lengthy hadith, we need only first sentence from it.

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ أَبِي أَيُّوبَ الْخَزَّازِ عَنْ أَبِي بَصِيرٍ

عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) أَنَّ آزَرَ أَبَا إِبْرَاهِيمَ ( عليه السلام )  كَانَ مُنَجِّماً لِنُمْرُودَ

” Narrated Ali ibn Ibrahim from his father, from ibn Abu Umeyr from Hisham ibn Salim from Abu Ayub al-Hazzari from Abu Abdullah (alaihi salam), which said: “Azar father of Ibrahim (alaihi salam) was astrologer of Namrud..”

Majlisi in his “Mirat” said this hadith is good (hasan).
