The Prophet ﷺ said, "Ibrahim will meet his father Azar on the Day of Resurrection, and there will be darkness and dust upon Azar's face. Ibrahim will say to him, 'Did I not tell you not to disobey me?' His father will reply, 'Today I will not disobey you.' Then Ibrahim will say, 'My Lord, You promised me that You would not disgrace me on the Day they are resurrected. What disgrace could be greater than that of my outcast father?' Allah, the Exalted, will say, 'I have forbidden Paradise to the disbelievers.' Then it will be said, 'Ibrahim, look at what is beneath your feet.' He will look, and behold, there will be a male hyena covered in filth. It will be seized by its legs and cast into the Fire."
عن النبي ﷺ قال: يلقى إبراهيم أباه آزر يوم القيامة وعلى وجه آزر قترة، وغبرة، فيقول له إبراهيم: ألم أقل لك: لا تعصني فيقول أبوه: فاليوم لا أعصيك. فيقول إبراهيم: يا رب إنك وعدتني أن لا تخزيني يوم يبعثون، فأي خزي أخزى من أبي الأبعد؟ فيقول الله تعالى: إني حرمت الجنة على الكافرين. ثم يقال: يا إبراهيم ما تحت رجليك؟ فينظر فإذا هو بذيخ ملتطخ، فيؤخذ بقوائمه فيلقى في النار.
Bukhari narrated it in the chapters on the Prophets (3350), from Ismail bin Abdullah, who said, "My brother Abdul-Hameed told me, from Ibn Abu Dhib, from Saeed Maqburi, from Abu Hurairah," and then he related it.The name of Ibrahim's father was Azar, as mentioned in the words of Allah Most High, "And when Ibrahim said to his father Azar" [Anaam 6:74], and this is the correct view that must be relied upon. As for his name in the so-called Torah, it is "Terah," Genesis (11:27).Hafiz bin Kathir, in al-Bidayah wan-Nihayah (1/329–330), quoted the view of the majority of genealogists, among them Ibn Abbas, that his father's name was "Tarih," while the People of the Book say "Tarikh," with a "kha." It has been said that he was given the nickname Azar after an idol he used to worship, which bore that name. Ibn Kathir said, "Ibn Jareer said, 'The correct view is that his name was Azar, and perhaps he had two proper names, or one of them was a nickname and the other his proper name.' What he said here is plausible."End of quote. As for the phrase "a filthy hyena," the "hyena" here refers to the male hyena.
