باب مَنْ تَكَفَّلَ عَنْ مَيِّتٍ، دَيْنًا فَلَيْسَ لَهُ أَنْ يَرْجِعَ
Sahih al-Bukhari 2296

Narrated Jabir bin `Abdullah:

Once the Prophet (ﷺ) said (to me), "If the money of Bahrain comes, I will give you a certain amount of it." The Prophet (ﷺ) had breathed his last before the money of Bahrain arrived. When the money of Bahrain reached, Abu Bakr announced, "Whoever was promised by the Prophet (ﷺ) should come to us." I went to Abu Bakr and said, "The Prophet (ﷺ) promised me so and so." Abu Bakr gave me a handful of coins and when I counted them, they were five-hundred in number. Abu Bakr then said, "Take twice the amount you have taken (besides).

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا عَمْرٌو، سَمِعَ مُحَمَّدَ بْنَ عَلِيٍّ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهم ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ لَوْ قَدْ جَاءَ مَالُ الْبَحْرَيْنِ، قَدْ أَعْطَيْتُكَ هَكَذَا وَهَكَذَا وَهَكَذَا ‏"‏‏.‏ فَلَمْ يَجِئْ مَالُ الْبَحْرَيْنِ حَتَّى قُبِضَ النَّبِيُّ صلى الله عليه وسلم فَلَمَّا جَاءَ مَالُ الْبَحْرَيْنِ أَمَرَ أَبُو بَكْرٍ فَنَادَى مَنْ كَانَ لَهُ عِنْدَ النَّبِيِّ صلى الله عليه وسلم عِدَةٌ أَوْ دَيْنٌ فَلْيَأْتِنَا‏.‏ فَأَتَيْتُهُ، فَقُلْتُ إِنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لِي كَذَا وَكَذَا، فَحَثَى لِي حَثْيَةً فَعَدَدْتُهَا فَإِذَا هِيَ خَمْسُمِائَةٍ، وَقَالَ خُذْ مِثْلَيْهَا‏.‏
