[Machine] Bashir, the Messenger of Allah ﷺ told me, and his name in the pre-Islamic era was Zahm ibn Ma'bad. He emigrated to the Messenger of Allah and asked him, "What is your name?" Zahm replied, "Zahm." The Messenger of Allah said, "No, rather your name is Bashir." So his name became Bashir. Abu Shayban, who is Aswad ibn Shayban, narrated the hadith and said, "I grabbed his hand and said, 'O Messenger of Allah, by my father and mother, I do not seek revenge against Allah.' So he mentioned the hadith and said, 'O companion of the two Sabtis, drop your two Sabtis.'"
حَدَّثَنِي بَشِيرُ رَسُولِ اللهِ ﷺ وَكَانَ اسْمُهُ فِي الْجَاهِلِيَّةِ زَحْمَ بْنَ مَعْبَدٍ فَهَاجَرَ إِلَى رَسُولِ اللهِ ﷺ فَسَأَلَهُ مَا اسْمُكَ؟ قَالَ زَحْمٌ قَالَ لَا بَلْ أَنْتَ بَشِيرٌ فَكَانَ اسْمَهُ قَالَ بَيْنَا أَنَا أُمَاشِي رَسُولَ اللهِ ﷺ إِذْ قَالَ يَا ابْنَ الْخَصَاصِيَةِ مَا أَصْبَحْتَ تَنْقِمُ عَلَى اللهِ؟ أَصْبَحْتَ تُمَاشِي رَسُولَ اللهِ قَالَ أَبُو شَيْبَانَ وَهُوَ الْأَسْوَدُ بْنُ شَيْبَانَ أَحْسَبُهُ قَالَ آخِذًا بِيَدِهِ فَقُلْتُ يَا رَسُولَ اللهِ بِأَبِي أَنْتَ وَأُمِّي مَا أَنْقِمُ عَلَى اللهِ شَيْئًا فَذَكَرَ الْحَدِيثَ وَقَالَ يَا صَاحِبَ السِّبْتِيَّتَيْنِ أَلْقِ سِبْتِيَّتَكَ
