Volume 9, Book 84, Number 58:
Narrated Abu Burda:
Abu Musa said, “I came to the Prophet along with two men (from the tribe) of Ash’ariyin, one on
my right and the other on my left, while Allah’s Apostle was brushing his teeth (with a Siwak), and
both men asked him for some employment. The Prophet said, ‘O Abu Musa (O ‘Abdullah bin Qais!).’ I
said, ‘By Him Who sent you with the Truth, these two men did not tell me what was in their hearts
and I did not feel (realize) that they were seeking employment.’ As if I were looking now at his Siwak
being drawn to a corner under his lips, and he said, ‘We never (or, we do not) appoint for our affairs
anyone who seeks to be employed. But O Abu Musa! (or ‘Abdullah bin Qais!) Go to Yemen.'” The
Prophet then sent Mu’adh bin Jabal after him and when Mu’adh reached him, he spread out a cush –
ion for him and requested him to get down (and sit on the cushion). Behold: There was a fettered
man beside Abu Muisa. Mu’adh asked, “Who is this (man)?” Abu Muisa said, “He was a Jew and be –
came a Muslim and then reverted back to Judaism.” Then Abu Muisa requested Mu’adh to sit down
but Mu’adh said, “I will not sit down till he has been killed. This is the judgment of Allah and His
Apostle (for such cases) and repeated it thrice. Then Abu Musa ordered that the man be killed, and
he was killed. Abu Musa added, “Then we discussed the night prayers and one of us said, ‘I pray and
sleep, and I hope that Allah will reward me for my sleep as well as for my prayers.'”
