Sahih al-Bukhari 4344, 4345

Narrated Abu Burda:

That the Prophet (ﷺ) sent his (i.e. Abu Burda’s) grandfather, Abu Musa and Mu`adh 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 Mu`adh 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.” Mu`adh 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. Mu`adh) pitched
a tent and they started visiting each other. Once Mu`adh paid a visit to Abu Musa and saw a chained
man. Mu`adh asked, “What is this?” Abu Musa said, “(He was) a Jew who embraced Islam and has
now turned apostate.” Mu`adh said, “I will surely chop off his neck!”
