Narrated `Aisha: Allah's Messenger bought some foodstuff from a Jew and mortgaged his armor to him.
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتِ اشْتَرَى رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ يَهُودِيٍّ طَعَامًا وَرَهَنَهُ دِرْعَهُ.
