Arabic (Original)
حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ الْهَاشِمِيُّ حَدَّثَنَا إِسْمَاعِيلُ يَعْنِي ابْنَ جَعْفَرٍ أَخْبَرَنِي الْعَلَاءُ عَنْ مَعْبَدِ بْنِ كَعْبٍ السُّلَمِيِّ عَنْ أَخِيهِ عَبْدِ اللَّهِ بْنِ كَعْبٍ عَنْ أَبِي أُمَامَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ اقْتَطَعَ حَقَّ امْرِئٍ مُسْلِمٍ بِيَمِينِهِ فَقَدْ أَوْجَبَ اللَّهُ لَهُ بِهَا النَّارَ وَحَرَّمَ عَلَيْهِ الْجَنَّةَ فَقَالَ لَهُ رَجُلٌ وَإِنْ كَانَ شَيْئًا يَسِيرًا يَا رَسُولَ اللَّهِ قَالَ وَإِنْ قَضِيبًا مِنْ أَرَاكٍ حَدَّثَنَا يَزِيدُ أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاقَ عَنْ مَعْبَدِ بْنِ كَعْبٍ فَذَكَرَ مِثْلَهُ إِلَّا أَنَّهُ قَالَ عَنْ أَبِي أُمَامَةَ بْنِ سَهْلٍ أَحَدِ بَنِي حَارِثَةَ قَالَ أَبُو عَبْد الرَّحْمَنِ هَذَا أَبُو أُمَامَةَ الْحَارِثِيُّ وَلَيْسَ هُوَ أَبَا أُمَامَةَ الْبَاهِلِيَّ.
English Translation
Sulayman ibn Dawud al-Hashimi told us, Isma'il -- meaning Ibn Ja'far -- told us, al-Ala' informed me, from Ma'bad ibn Ka'b al-Sulami, from his brother Abdullah ibn Ka'b, from Abu Umamah, that the Prophet, peace and blessings be upon him, said: "Whoever cuts off the right of a Muslim by his oath, Allah has made the Fire obligatory for him and forbidden him Paradise." A man said to him, "Even if it be something trifling, O Messenger of Allah?" He said: "Even if it be a twig of arak-wood." Yazid told us, Muhammad ibn Ishaq informed us, from Ma'bad ibn Ka'b -- and he mentioned the like of it, except that he said "from Abu Umamah ibn Sahl, one of the Banu Haritha." Abu Abd al-Rahman said: This is Abu Umamah al-Harithi, and he is not Abu Umamah al-Bahili.
