Who are the companions of the two ships who came to Medina from Abyssinia with Mu'ammar ibn Abdullah ibn Nadhlah al-Qurashi al-'Adawi?

Two ships arrived to the Prophet, peace and blessings be upon him, at the time of the فتح خيبر (Conquest of Khaybar): one belonged to the Ash'aris, and the other to Ja'far and his companions. Ibn Ishaq mentioned that Abu Musa al-Ash'ari and those with him disembarked in Abyssinia after the wind cast their ship there. Then they departed from Abyssinia with Ja'far and his companions, and they all arrived to the Prophet, peace and blessings be upon him, at the time of the Conquest of Khaybar, and he distributed shares to them.
