Major tribes, including Himyar, sent delegations to Medina during the "year of delegations" around 630–631 CE. Several Yemenis accepted Islam before the year 630, such as Ammar ibn Yasir, Al-Ala'a Al-Hadrami, Miqdad ibn Aswad, Abu Musa Ashaari, and Sharhabeel ibn Hasana. A man named 'Abhala ibn Ka'ab Al-Ansi expelled the remaining Persians and claimed he was a prophet of Rahman. He was assassinated by a Yemeni of Persian origin called Fayruz al-Daylami. Christians, who were mainly staying in Najran along with Jews, agreed to pay ''jizyah'' (), although some Jews converted to Islam, such as Wahb ibn Munabbih and Ka'ab al-Ahbar.
