It was narrated from Muhammad bin Hamzah bin Yusuf bin 'Abdullah bin Salam, from his father, that his grandfather 'Abdullah bin Salam said:
"A man came to the Prophet ﷺ and said, 'The tribe of Banu so-and- so, who were descended from the Jews, have become Muslim, and they are starving, and I am afraid that they may apostatize.' The Prophet ﷺ said: 'Who has something with him?' A Jewish man said: 'I have such and such, and he named it, and I think he said three hundred Dinar for such and such 'an amount (of produce) from the garden of the tribe of Banu so-and-so.' The Messenger of Allah ﷺ said: 'For such and such a price at such and such a time, but not from the garden of the tribe of Banu so-and- so."'

حَدَّثَنَا يَعْقُوبُ بْنُ حُمَيْدِ بْنِ كَاسِبٍ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، عَنْ مُحَمَّدِ بْنِ حَمْزَةَ بْنِ يُوسُفَ بْنِ عَبْدِ اللَّهِ بْنِ سَلاَمٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ عَبْدِ اللَّهِ بْنِ سَلاَمٍ، قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ بَنِي فُلاَنٍ أَسْلَمُوا - لِقَوْمٍ مِنَ الْيَهُودِ - وَإِنَّهُمْ قَدْ جَاعُوا فَأَخَافُ أَنْ يَرْتَدُّوا . فَقَالَ النَّبِيُّ ﷺ " مَنْ عِنْدَهُ " . فَقَالَ رَجُلٌ مِنَ الْيَهُودِ عِنْدِي كَذَا وَكَذَا - لِشَىْءٍ قَدْ سَمَّاهُ أُرَاهُ قَالَ ثَلاَثُمِائَةِ دِينَارٍ بِسِعْرِ كَذَا وَكَذَا مِنْ حَائِطِ بَنِي فُلاَنٍ . فَقَالَ رَسُولُ اللَّهِ ﷺ " بِسِعْرِ كَذَا وَكَذَا إِلَى أَجَلِ كَذَا وَكَذَا وَلَيْسَ مِنْ حَائِطِ بَنِي فُلاَنٍ " .
