Sunan Ibn Majah, Hadith 2436 ⓘ
It was narrated from 'Aisha that : the Messenger of Allah bought some food from a Jew with payment to be made later, and he pawned his armor for that.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، حَدَّثَنِي الأَسْوَدُ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم اشْتَرَى مِنْ يَهُودِيٍّ طَعَامًا إِلَى أَجَلٍ وَأَرْهَنَهُ دِرْعَهُ .
