حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى الرَّازِيُّ، أَخْبَرَنَا عِيسَى، حَدَّثَنَا أُسَامَةُ، عَنْ عَبْدِ اللَّهِ بْنِ رَافِعٍ، قَالَ سَمِعْتُ أُمَّ سَلَمَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِهَذَا الْحَدِيثِ قَالَ يَخْتَصِمَانِ فِي مَوَارِيثَ وَأَشْيَاءَ قَدْ دَرَسَتْ فَقَالَ " إِنِّي إِنَّمَا أَقْضِي بَيْنَكُمْ بِرَأْيِي فِيمَا لَمْ يُنْزَلْ عَلَىَّ فِيهِ
Translation
Umm Salamah reported the Prophet (ﷺ) as saying when two men were disputing over inheritance and old things
They were disputing concerning inheritances and things that had become worn out, and he said: "Verily, I only judge between you according to my opinion in matters concerning which nothing has been revealed to me."
