Narrated Abu Musa: The news of the migration of the Prophet (from Mecca to Medina) reached us while we were in Yemen. So we set out as emigrants towards him. We were (three) I and my two brothers. I was the youngest of them, and one of the two was Abu Burda, and the other, Abu Ruhm, and our total number was either 53 or 52 men from my people. We got on board a boat and our boat took us to Negus in Ethiopia. There we met Ja'far bin Abi Talib and stayed with him. Then we all came (to Medina) and met the Prophet at the time of the conquest of Khaibar. Some of the people used to say to us, namely the people of the ship, "We have migrated before you." Asma' bint 'Umais who was one of those who had come with us, came as a visitor to Hafsa, the wife the Prophet . She had migrated along with those other Muslims who migrated to Negus. 'Umar came to Hafsa while Asma' bint 'Umais was with her. 'Umar, on seeing Asma,' said, "Who is this?" She said, "Asma' bint 'Umais," 'Umar said, "Is she the Ethiopian? Is she the sea-faring lady?" Asma' replied, "Yes." 'Umar said, "We have migrated before you (people of the boat), so we have got more right than you over Allah's Apostle " On that Asma' became angry and said, "No, by Allah, while you were with Allah's Apostle who was feeding the hungry ones amongst you, and advised the ignorant ones amongst you, we were in the far-off hated land of Ethiopia, and all that was for the sake of Allah's Apostle . By Allah, I will neither eat any food nor drink anything till I inform Allah's Apostle of all that you have said. There we were harmed and frightened. I will mention this to the Prophet and will not tell a lie or curtail your saying or add something to it." So when the Prophet came, she said, "O Allah's Prophet 'Umar has said so-and-so." He said (to Asma'), "What did you say to him?" Asma's aid, "I told him so-and-so." The Prophet said, "He (i.e. 'Umar) has not got more right than you people over me, as he and his companions have (the reward of) only one migration, and you, the people of the boat, have (the reward of) two migrations." Asma' later on said, "I saw Abu Musa and the other people of the boat coming to me in successive groups, asking me about this narration,, and to them nothing in the world was more cheerful and greater than what the Prophet had said about them." Narrated Abu Burda: Asma' said, "I saw Abu Musa requesting me to repeat this narration again and again." Narrated Abu Burda: Abu Musa said, "The Prophet said, "I recognize the voice of the group of Al-Ashariyun, when they recite the Qur'an, when they enter their homes at night, and I recognize their houses by (listening) to their voices when they are reciting the Qur'an at night although I have not seen their houses when they came to them during the day time. Amongst them is Hakim who, on meeting the cavalry or the enemy, used to say to them (i.e. the enemy). My companions order you to wait for them.' "
