Sahih al-Bukhari 2287

Al-Hawala (the transference of a debt from one person to another. It is an agreement whereby a debtor is released from a debt by another becoming responsible for it). Can Hawala be rejected by the creditors after accepting it?
Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏مَطْلُ الْغَنِيِّ ظُلْمٌ، فَإِذَا أُتْبِعَ أَحَدُكُمْ عَلَى مَلِيٍّ فَلْيَتْبَعْ ‏"
Translation
Narrated Abu Huraira

The Prophet (ﷺ) said, "Procrastination (delay) in paying debts by a wealthy man is injustice. So, if your debt is transferred from your debtor to a rich debtor, you should agree."
