Sunan Ibn Majah 53
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَزِيدَ، عَنْ سَعِيدِ بْنِ أَبِي أَيُّوبَ، حَدَّثَنِي أَبُو هَانِئٍ، حُمَيْدُ بْنُ هَانِئٍ الْخَوْلاَنِيُّ عَنْ أَبِي عُثْمَانَ، مُسْلِمِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ أُفْتِيَ بِفُتْيَا غَيْرَ ثَبَتٍ فَإِنَّمَا إِثْمُهُ عَلَى مَنْ أَفْتَاهُ " .
Abu Bakr ibn Abi Shaybah narrated to us: Abdullah ibn Yazid narrated to us, from Said ibn Abi Ayyub: Abu Hani, Humayd ibn Hani al-Khawlani, narrated to me, from Abu Uthman, Muslim ibn Yasar, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings be upon him) said: Whoever is given a legal opinion without sound basis, its sin is only upon the one who gave him that opinion.
Translation notes
The Arabic characterizes the legal opinion as ghayr thabit, not firmly established. It places the sin of giving such an unsupported opinion on the one who issued it.
