حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو الأَحْوَصِ، حَدَّثَنَا شَبِيبُ بْنُ غَرْقَدَةَ، عَنْ سُلَيْمَانَ بْنِ عَمْرٍو، عَنْ أَبِيهِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ يَقُولُ ‏"‏ أَلاَ إِنَّ كُلَّ رِبًا مِنْ رِبَا الْجَاهِلِيَّةِ مَوْضُوعٌ لَكُمْ رُءُوسُ أَمْوَالِكُمْ لاَ تَظْلِمُونَ وَلاَ تُظْلَمُونَ ‏.‏ أَلاَ وَإِنَّ كُلَّ دَمٍ مِنْ دَمِ الْجَاهِلِيَّةِ مَوْضُوعٌ وَأَوَّلُ دَمٍ أَضَعُ مِنْهَا دَمُ الْحَارِثِ بْنِ عَبْدِ الْمُطَّلِبِ ‏"‏ ‏.‏ كَانَ مُسْتَرْضَعًا فِي بَنِي لَيْثٍ فَقَتَلَتْهُ هُذَيْلٌ ‏.‏ قَالَ ‏"‏ اللَّهُمَّ هَلْ بَلَّغْتُ ‏"‏ ‏.‏ قَالُوا نَعَمْ ‏.‏ ثَلاَثَ مَرَّاتٍ ‏.‏ قَالَ ‏"‏ اللَّهُمَّ اشْهَدْ ‏"‏ ‏.‏ ثَلاَثَ مَرَّاتٍ ‏.‏

Narrated Sulaiman b. 'Amr: On the authority of his father: I heard the Messenger of Allah (PBUH) say in the Farewell Pilgrimage: "Lo, all claims to usury of the pre-Islamic period have been abolished. You shall have your capital sums, deal not unjustly and you shall not be dealt with unjustly. Lo, all claims for blood-vengeance belonging to the pre-Islamic period have been abolished. The first of those murdered among us whose blood-vengeance I remit is al-Harith ibn AbdulMuttalib, who suckled among Banu Layth and killed by Hudhayl." He then said: O Allah, have I conveyed the message? They said: Yes, saying it three times. He then said: O Allah, be witness, saying it three times. Translation Not Available
