Sahih Muslim Hadith 4718

I went to the Prophet ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and with me were two men from the Ash'ari tribe. One of them was on my right hand and the other on my left. Both of them made a request for a position (of authority) while the Prophet ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) was brushing his teeth with a tooth-stick. He said (to me): Abu Musa رضی اللہ عنہ (or 'Abdullah bin Qais), what do you say (about the request they have made)? I said: By God Who sent thee on thy mission with truth, they did not disclose to me what they had in their minds, and I did not know that they would ask for a position. The narrator says (while recalling this hadith): I visualise as if I were looking at the miswak of the Prophet ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) between his lips. He (the Holy Prophet) said: We shall not or shall never appoint to the public offices (in our State) those who with to have them, but you may go, Abu Musa (or Abdullah bin Qais) (to take up your assignment). He sent him to Yemen as governor. then he sent Mu'adh bin jabal رضی اللہ عنہ in his wake (to help him in the discharge of duties). When Mu'adh reached the camp of Abu Musa, the latter (received him and) said: Please get yourself down; and he spread for him a mattress, while there was a man bound hand and foot as a prisoner. Mu'adh رضی اللہ عنہ said: Who is this? Abu Musa رضی اللہ عنہ said: He was a Jew. He embraced Islam. Then he reverted to his false religion and became a Jew. Mu'adh رضی اللہ عنہ said: I won't sit until he is killed according to the decree of Allah and His Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) (in this case). Abu Musa رضی اللہ عنہ said: Be seated. It will be done. He said: I won't sit unless he is killed in accordance with the decree of Allah and His Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). He repeated these words thrice. Then Abu Musa رضی اللہ عنہ ordered him (to be killed) and he was kilied. Then the two talked of standing in prayer at night. One of them, i.e. Mu'adh رضی اللہ عنہ, said: I sleep (for a part of the night) and stand in prayer (for a part) and I hope that I shall get the same reward for steeping as I shall get for standing (in prayer).
