باب مَنِ اشْتَرَى بِالدَّيْنِ وَلَيْسَ عِنْدَهُ ثَمَنُهُ، أَوْ لَيْسَ بِحَضْرَتِهِ
Sahih al-Bukhari 2386

Narrated Al-A`mash:

When we were with Ibrahim, we talked about mortgaging in deals of Salam. Ibrahim narrated from Aswad that `Aisha had said, "The Prophet (ﷺ) bought some foodstuff on credit from a Jew and mortgaged an iron armor to him."

حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا الأَعْمَشُ، قَالَ تَذَاكَرْنَا عِنْدَ إِبْرَاهِيمَ الرَّهْنَ فِي السَّلَمِ فَقَالَ حَدَّثَنِي الأَسْوَدُ عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم اشْتَرَى طَعَامًا مِنْ يَهُودِيٍّ إِلَى أَجَلٍ، وَرَهَنَهُ دِرْعًا مِنْ حَدِيدٍ‏.‏
