That the Prophet ﷺ sent his (i.e. Abu Burda's) grandfather, Abu Musa and Muʿadh to Yemen and said to both of them "Facilitate things for the people (Be kind and lenient) and do not make things difficult (for people), and give them good tidings, and do not repulse them and both of you should obey each other." Abu Musa said, "O Allah's Prophet! In our land there is an alcoholic drink (prepared) from barley called Al-Mizr, and another (prepared) from honey, called Al-Bit"' The Prophet ﷺ said, "All intoxicants are prohibited." Then both of them proceeded and Muʿadh asked Abu Musa, "How do you recite the Qur'an?" Abu Musa replied, "I recite it while I am standing, sitting or riding my riding animals, at intervals and piecemeal." Muʿadh said, "But I sleep and then get up. I sleep and hope for Allah's Reward for my sleep as I seek His Reward for my night prayer." Then he (i.e. Muʿadh) pitched a tent and they started visiting each other. Once Muʿadh paid a visit to Abu Musa and saw a chained man. Muʿadh asked, "What is this?" Abu Musa said, "(He was) a Jew who embraced Islam and has now turned apostate." Muʿadh said, "I will surely chop off his neck!"
