أَخْبَرَنَا أَبُو الأَزْهَرِ النَّيْسَابُورِيُّ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنِ الْحَكَمِ، عَنْ مُجَاهِدٍ، عَنْ أَيْمَنَ، قَالَ لَمْ تُقْطَعِ الْيَدُ فِي زَمَنِ رَسُولِ اللَّهِ صلى الله عليه وسلم إِلاَّ فِي ثَمَنِ الْمِجَنِّ وَقِيمَةُ الْمِجَنِّ يَوْمَئِذٍ دِينَارٌ .
