Narrated Mu'adh ibn Jabal:AbuMusa said: Mu'adh came to me when I was in the Yemen. A man who was Jew embraced Islam and then retreated from Islam. When Mu'adh came, he said: I will not come down from my mount until he is killed. He was then killed. One of them said: He was asked to repent before that.
حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا الْحِمَّانِيُّ، - يَعْنِي عَبْدَ الْحَمِيدِ بْنَ عَبْدِ الرَّحْمَنِ - عَنْ طَلْحَةَ بْنِ يَحْيَى، وَبُرَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ قَدِمَ عَلَىَّ مُعَاذٌ وَأَنَا بِالْيَمَنِ، وَرَجُلٌ، كَانَ يَهُودِيًّا فَأَسْلَمَ فَارْتَدَّ عَنِ الإِسْلاَمِ، فَلَمَّا قَدِمَ مُعَاذٌ قَالَ لاَ أَنْزِلُ عَنْ دَابَّتِي حَتَّى يُقْتَلَ . فَقُتِلَ . قَالَ أَحَدُهُمَا وَكَانَ قَدِ اسْتُتِيبَ قَبْلَ ذَلِكَ .
