Chapter 2 If somebody's debt are transferred to a rich debtor
باب إِذَا أَحَالَ عَلَى مَلِيٍّ فَلَيْسَ لَهُ رَدٌّ
Narrated Abu Huraira:
The Prophet (ﷺ) said, "Procrastination (delay) in paying debts by a wealthy person is injustice. So, if your debt is transferred from your debtor to a rich debtor, you should agree."
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ ذَكْوَانَ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَطْلُ الْغَنِيِّ ظُلْمٌ، وَمَنْ أُتْبِعَ عَلَى مَلِيٍّ فَلْيَتَّبِعْ ".
