It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) wrote a letter to one of the tribes of the Arabs, inviting them to Islam, but they did not accept the letter, and (the messenger) returned to the Messenger of Allah (peace and blessings be upon him) and informed him. At that he (peace and blessings be upon him) said: "Indeed, had I sent it to the people living on the coast of Oman, of Azd Shanu'ah and Aslam, they would certainly have accepted it." Then the Messenger of Allah (peace and blessings be upon him) sent a message to al-Julanda inviting him to Islam, and he accepted it and embraced Islam, and he sent a gift to the Messenger of Allah (peace and blessings be upon him). The gift arrived when the Messenger of Allah (peace and blessings be upon him) had already passed away, so Sayyiduna Abu Bakr (may Allah be pleased with him) treated the gift as inheritance and divided it between Sayyidah Fatimah (may Allah be pleased with her) and Sayyiduna al-Abbas (may Allah be pleased with him).
