It was narrated that Jabir bin 'Abdullah said:
"I was with the Prophet ﷺ on a military campaign, and he said to me: 'Will you sell this camel of yours for a Dinar?' I said: 'O Messenger of Allah, it is yours when I get to Al-Madinah.' He said: 'Then sell it for two Dinar, may Allah forgive you.' And he kept increasing the price for me, saying: 'May Allah forgive you,' each time, until the amount reached twenty Dinar. When I came to Al-Madinah, I took hold of the camel's head and brought it to the Prophet ﷺ and he said: 'O Bilal, give him twenty Dinar from the spoils of war.' And he said: 'Take your camel away and go to your people with it.'"

حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنِ الْجُرَيْرِيِّ، عَنْ أَبِي نَضْرَةَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كُنْتُ مَعَ النَّبِيِّ ﷺ فِي غَزْوَةٍ فَقَالَ لِي " أَتَبِيعُ نَاضِحَكَ هَذَا بِدِينَارٍ وَاللَّهُ يَغْفِرُ لَكَ " . قُلْتُ يَا رَسُولَ اللَّهِ هُوَ نَاضِحُكُمْ إِذَا أَتَيْتُ الْمَدِينَةَ . قَالَ " فَتَبِيعُهُ بِدِينَارَيْنِ وَاللَّهُ يَغْفِرُ لَكَ " . قَالَ فَمَا زَالَ يَزِيدُنِي دِينَارًا دِينَارًا وَيَقُولُ مَكَانَ كُلِّ دِينَارٍ " وَاللَّهُ يَغْفِرُ لَكَ " . حَتَّى بَلَغَ عِشْرِينَ دِينَارًا فَلَمَّا أَتَيْتُ الْمَدِينَةَ أَخَذْتُ بِرَأْسِ النَّاضِحِ فَأَتَيْتُ بِهِ النَّبِيَّ ﷺ فَقَالَ " يَا بِلاَلُ أَعْطِهِ مِنَ الْعَيْبَةِ عِشْرِينَ دِينَارًا " . وَقَالَ " انْطَلِقْ بِنَاضِحِكَ وَاذْهَبْ بِهِ إِلَى أَهْلِكَ " .
