Al-Bukhārī narrated (1): “Ismāʿīl b. ʿAbd-Allāh related to us; my brother ʿAbd al-Ḥamīd told me, from Ibn Abī Dhiʾb, from Saʿīd al-Maqburī, from Abū Hurayrah—may Allah be pleased with him—that the Prophet ﷺ said:
‘Abraham will meet his father Āzar on the Day of Resurrection, and on Āzar’s face will be darkness and dust. Abraham will say, “Did I not tell you, ‘Do not disobey me’?” His father will answer, “Today I shall not disobey you.” Abraham will then say, “My Lord, You promised me that You would not disgrace me on the day they are raised; what disgrace could be greater than for my distant father to be cast away?” Allah will reply, “I have forbidden Paradise to the unbelievers.” It will then be said, “O Abraham, what is beneath your feet?” He will look, and behold: it is a blood-smeared hyena. It will be seized by its legs and thrown into the Fire.’
Thus al-Bukhārī recorded it on its own in the story of Abraham.
He also cited it in his Tafsīr (2): Ibrāhīm b. Ṭahmān, from Ibn Abī Dhiʾb, from Saʿīd al-Maqburī, from his father, from Abū Hurayrah.
Al-Nasāʾī likewise transmitted it (3): from Aḥmad b. Ḥafṣ (4) b. ʿAbd-Allāh, from his father, from Ibrāhīm b. Ṭahmān, with this chain.
Al-Bazzār narrated it as well (5): through Ḥammād b. Salamah, from Ayyūb, from Muḥammad b. Sīrīn, from Abū Hurayrah, from the Prophet ﷺ, in similar wording—though its context is somewhat unusual. It was also related (6) through Qatādah, from ʿUqbah b. ʿAbd al-Ghāfir, from Abū Saʿīd, from the Prophet ﷺ, likewise.
Allah, Exalted is He, says: “And when Abraham said to his father Āzar, ‘Do you take idols for gods? Truly I see you and your people in manifest error.’” (al-Anʿām 6:74)
This indicates that Abraham’s father’s name was Āzar. The majority of genealogists—including Ibn ʿAbbās—hold that his name was Tāriḥ, while the People of the Book say Tāriḫ (with a khāʾ). It has been suggested that he was given the epithet Āzar after an idol he used to worship by that name.
Ibn Jarīr (7) said: “The correct view is that his name was Āzar; perhaps he had two proper names, or one was a nickname and the other his given name.”
What he stated is plausible, and Allah knows best.
