4071. It was narrated from Abū Burdah bin Abī Mūsā Al-Ash'arī, from his father: "That the Prophet ﷺ sent him to Yemen, then he sent Mu'ādḥ bin Jabal after that. When he arrived he said: 'O people, I am the envoy of the Messenger of Allāh to you.' Abū Mūsā gave him a cushion to sit down, then a man was brought who had been a Jew, then he became a Muslim, then he reverted to Kufr. Mu'ādhd said: 'I will not sit down until he is killed; this is the decree of Allāh and His Messenger,' (saying it) three times. When he was killed, he sat down." (Saḥīḥ)
