Abu Musa Ashari reported,

I came to the Prophet ﷺ accompanied by two men from the Asharis, one on my right and the other on my left, while the Messenger of Allah ﷺ was using the tooth-stick. Both of them asked him for an appointment.He said, "Abu Musa," or "Abdullah bin Qays."I said, "By the One who sent you with the truth, they did not inform me of what was in their hearts, and I did not realize they were seeking a position."It is as if I am still looking at his tooth-stick beneath his lip, which had drawn back.He said, "We will never," or "We do not appoint to our work anyone who seeks it. But you go, Abu Musa," or "Abdullah bin Qays, to Yemen."Then he sent Muaz bin Jabal to follow him. When Muaz arrived, Abu Musa laid out a cushion for him and said, "Dismount."There was a man with him, bound in chains.Muaz asked, "Who is this?"Abu Musa replied, "He was a Jew who embraced Islam, then reverted to Judaism."Muaz said, "Sit down."He said, "I will not sit until he is killed. This is the judgment of Allah and His Messenger," repeating it three times.So the order was given, and the man was executed.Then the two of them discussed standing in prayer at night. One of them said, "As for me, I stand in prayer and I sleep, and I hope from my sleep what I hope from my standing."

عن أبي موسى قال

أقبلت إلى النبي ﷺ ومعي رجلان من الأشعريين أحدهما عن يميني والآخر عن يساري ورسول الله ﷺ يستاك فكلاهما سأل فقال يا أبا موسى أو يا عبد الله بن قيس قال قلت والذي بعثك بالحق ما أطلعاني على ما في أنفسهما وما شعرت أنهما يطلبان العمل فكأني أنظر إلى سواكه تحت شفته قلصت فقال لن أو لا نستعمل على عملنا من أراده ولكن اذهب أنت يا أبا موسى أو يا عبد الله بن قيس إلى اليمن ثم اتبعه معاذ بن جبل فلما قدم عليه ألقى له وسادة قال انزل وإذا رجل عنده موثق قال ما هذا قال كان يهوديا فأسلم ثم تهود قال اجلس قال لا أجلس حتى يقتل قضاء الله ورسوله ثلاث مرات فأمر به فقتل ثم تذاكرا قيام الليل فقال أحدهما أما أنا فأقوم وأنام وأرجو في نومتي ما أرجو في قومتي
