That the Prophet (ﷺ) 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.
Jami` at-Tirmidhi Book 14, Hadith 111
← Previous Hadith That the Messenger of Allah (ﷺ) said: "A man among those before you was called to reckon and nothing good was found with him. Except that he was a wealthy man so he used to mix with the pople and he would tell his servant to be lenient with the insolvent. So Allah, Mighty and Sublime is He, said: 'We are more worthy of that than him, so be lenient with him.'"

This Hadith is Hasan Sahih. Abu Al-Yasar is Ka'b bin 'Amr.

Jami` at-Tirmidhi Book 14, Hadith 110 Next Hadith → That the Prophet (ﷺ) said: "Procrastination (in paying a debt) by a rich person is oppression. So if your debt is transfered from your debtor you should agree, and do not make two sales in one sale."

The Hadith is the Abu Hurairah (no. 1308) is a Hasan Sahih Hadith. And its meaning is that when the debt of one of you is transferred then agree. Some of the people of knowledge said when a man is offered to transfer his debt to a rich man and he does so, then the transferor is free of it, he is not to seek its return from the transferor. This is the view of Ash-Shafi'i, Ahmad, and Ishaq. Some of the people of knowledge said: "When this wealth could not be collected due to bankruptcy of the one it was transferred to, then he may seek its return to the first one." They argue this view with the saying of 'Uthman and others, when they said: "There is nothing due on a Muslim's wealth that is lost." Ishaq said: "The meaning of this Hadith: 'There is nothing due on a Muslim's wealth that is lost' this is when a man transfers it to another whom he thinks is wealthy, then he becomes bankrupt, so there is nothing due on the Muslim's wealth that is lost."
