Sa'id ibn Yahya ibn Sa'id al-Umawi narrated to me, he said: My father narrated to me, he said: Talhah ibn Yahya narrated to us, he said: Abu Burdah ibn Abi Musa narrated to me, from his father, who said: We set out toward the Messenger of Allah (may Allah bless him and grant him peace) by sea until we came to Makkah. My brothers were with me: Abu 'Amir ibn Qays, Abu Ruhm ibn Qays, and Muhammad ibn Qays, [along with] fifty of the Ash'ariyyin and six from 'Akk. Then we migrated by sea until we came to Al-Madinah.
