حَدَّثَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ فِي خُطْبَتِهِ ‏"‏ أَوْفُوا بِحِلْفِ الْجَاهِلِيَّةِ فَإِنَّهُ لاَ يَزِيدُهُ يَعْنِي الإِسْلاَمَ إِلاَّ شِدَّةً وَلاَ تُحْدِثُوا حِلْفًا فِي الإِسْلاَمِ ‏"‏ ‏.‏ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَأُمِّ سَلَمَةَ وَجُبَيْرِ بْنِ مُطْعِمٍ وَأَبِي هُرَيْرَةَ وَابْنِ عَبَّاسٍ وَقَيْسِ بْنِ عَاصِمٍ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏

Narrated 'Amr bin Shu'aib: From his father, from his grandfather, that the Messenger of Allah (PBUH) said during his Khutbah: "Fulfill the allegiances sworn in Jahiliyyah for it" - meaning Islam - "does not add to them except in gravity. And do not initiate new allegiances in Islam." [He said:] There are narration on this topic from 'Abdur-Rahman bin 'Awf, Umm Salamah, Jubair bin Mut'im, Abu Hurairah, Ibn 'Abbas, and Qais bin 'Asim. [Abu 'Eisa said:] This Hadith is Hasan Sahih. Translation Not Available
