I have an opinion , Irahim/Abraham (pbuh) born Ishmeal (pbuh) from Hajar and Isaac (pbuh) from Sara
Ishmeal (pbuh) came first, then Isaac (pbuh) came . so the Arab race came first then the Jew ,
Salam
It is said that Ismael is the ancestor of arabs, but Abraham was not an arab nor Hajar, who was an egyptian.
A long time ago i've seen a video where the cheikh said that Ismael and Hajar lived in Saudi Arabia and that Ismael married an arab woman. Meaning arabs already existed.
In the Quran you have the prophete Salih who is supposed to be an arab. Some said it was the Shelah of the Bible.
It was long ago before Ismael.
You also have Houd who lived long ago before Ismael and it is said he was an arab. Some say Houd is the Heber of the Bible.
ʿĀd was an ancient Arab tribe and a district in South Arabia that was led by 'Ad ibn Kin'ad.
The ʿĀd tribe settled in an area to the East of the Qahtan tribe and established the Kingdom of ʿĀd in South Arabia sometime between 10th century BC and 3rd century AD.
The 'Adid are mentioned in the Qur'an as being the people to whom the Islamic prophet Hud (هود) was sent by Allah to guide them back to the righteous path of faith.
ʿĀd - Wikipedia, the free encyclopedia
So arabs already existed before Ismael.
You said that Isaac is a jew, but the Quran said that neither Abraham, Ismael, Isaac, Jacob, Joseph and the Tribes were jews. Because Judaisme is a religion who came at Moses time.
But the Hebrews i think (maybe it's wrong) are originally the people of Abraham who lived in Mesopotamia, so they may be as old as the arab.
I don't think we can start with Ismael or Isaac to say who is the "older".
