What happened to Ashab Al-Okhdud?

Answer 1

It is unclear what the question is asking.

Story

If it is asking what the story of Ashab Al-Okhdud is, it is the following. It is unclear if these events are strictly historical since there is no supporting evidence (other than the Qur'an and the Faqih).

Before the Rise of Islam, there was a Jewish Kingdom in the Yemeni (now Saudi) city of Najran led by Dhu Nawas. There was a battle and the Christian community of Najran were brutally massacred at Dhu Nawas' orders. King Negus of the Christian Kingdom of Abyssinia (now Ethiopia) intervened to protect the Yemeni Christians and annex the territory. He was successful and Abyssinia held onto Yemen until the War of the Elephant, which took place at around 570 C.E.

Aftermath

If it is asking what happened to the Christians and Jews described in the Ashab Al-Okhdud, it becomes very unclear.

The Christian community in Yemen did not survive long after the conquest of Mecca and the unification of the Arabian Peninsula by Islam. Some credit it to mass conversion, some credit it to flight across the Gulf of Aden to Ethiopia, and some credit it to the Pact of Omar which ostensibly evicted Christians from the entire Arabian Peninsula.

As for the Jews, there did remain a small contingent of Jews in Yemen through most of Yemen's history (until they were airlifted to Israel). However, Yemeni Jews were very marginalized in Yemeni society, both under the Zaydi Shiites and the Sunnis.
