Jami` at-Tirmidhi, Volume 3, Book 12, Hadith 1308 (DarusSalam) ⓘ
Narrated Abu Hurairah: That the Prophet said: "Procrastination (in paying a debt) by a rich person is oppression. So if your debt is transferred from your debtor to a rich debtor, you should agree." He said: There are narrations on this topic from Ibn 'Umar, and Ash-Sharid bin Suwaid Ath-Thaqafi.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَطْلُ الْغَنِيِّ ظُلْمٌ وَإِذَا أُتْبِعَ أَحَدُكُمْ عَلَى مَلِيٍّ فَلْيَتْبَعْ " . قَالَ وَفِي الْبَابِ عَنِ ابْنِ عُمَرَ وَالشَّرِيدِ بْنِ سُوَيْدٍ الثَّقَفِيِّ .
