'A'isha (Allah be pleased with her) reported that Messenger of Allah ﷺ bought some grain from a Jew on credit and gave him a coat-of- mail of his as a pledge.  

قَالَتِ اشْتَرَى رَسُولُ اللَّهِ ﷺ مِنْ يَهُودِيٍّ طَعَامًا بِنَسِيئَةٍ فَأَعْطَاهُ دِرْعًا لَهُ رَهْنًا  

Messenger of Allah ﷺ bought from a Jew grain (as loan) and pledged him his iron coat-of-mail.  

قَالَتِ اشْتَرَى رَسُولُ اللَّهِ ﷺ مِنْ يَهُودِيٍّ طَعَامًا وَرَهَنَهُ دِرْعًا مِنْ حَدِيدٍ  

'A'isha (Allah be pleased with her) reported that Messenger of Allah ﷺ bought from a Jew grain for a specified time; and gave him iron coat-of-mail of his as a pledge.  

ذَكَرْنَا الرَّهْنَ فِي السَّلَمِ عِنْدَ إِبْرَاهِيمَ النَّخَعِيِّ فَقَالَ حَدَّثَنَا الأَسْوَدُ بْنُ يَزِيدَ عَنْ عَائِشَةَ أَنَّ رَسُولَ اللَّهِ ﷺ اشْتَرَى مِنْ يَهُودِيٍّ طَعَامًا إِلَى أَجَلٍ وَرَهَنَهُ دِرْعًا لَهُ مِنْ حَدِيدٍ  

This hadith has been narrated on the authority of 'A'isha (Allah be pleased with her), through another chain ol transmitters, but no mention was made of (its being made) of iron.  

عَنِ النَّبِيِّ ﷺ مِثْلَهُ وَلَمْ يَذْكُرْ مِنْ حَدِيدٍ
