(1) باب مَنِ اشْتَرَى بِالدَّيْنِ وَلَيْسَ عِنْدَهُ ثَمَنُهُ، أَوْ لَيْسَ بِحَضْرَتِهِ
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."
