Abdullah bin Umar reported,
I heard the Messenger of Allah ﷺ say, "Whoever's intercession stands in the way of one of the prescribed punishments of Allah 
has opposed Allah in His command. Whoever dies owing a debt will not repay it with Dinars or dirhams, but with good deeds and bad deeds. Whoever disputes on behalf of falsehood, knowing it to be false, remains under the wrath of Allah until he desists. And whoever says about a believer what is not true of him, Allah will make him dwell in the mire of foul pus until he retracts what he said."
Azami 5596
Sahihعن ابن عمر قال
سمعت رسول الله ﷺ يقول: من حالت شفاعته دون حد من حدود الله -عز وجل- فقد ضاد الله في أمره. ومن مات وعليه دين فليس بالدينار ولا بالدرهم، ولكنها الحسنات والسيئات. ومن خاصم في باطل -وهو يعلمه- لم يزل في سخط الله حتى ينزع. ومن قال في مؤمن ما ليس فيه أسكنه الله ردغة الخبال حتى يخرج مما قال.
Imam Ahmad narrated it (5385) from Hasan bin Musa, who said, Zuhayr bin Muawiya narrated to us, Umara bin Ghaziya narrated to us, from Yahya bin Rashid, who said, "We set out as pilgrims, ten men from the people of Syria, until we came to Makkah." Then he mentioned the hadith. He said, "So we came to him," meaning Ibn Umar, "and he came out to us." Then he mentioned the hadith.Hakim graded it sahih (272), and Bayhaqi also transmitted it (6/82), both of them through the route of Zuhayr bin Muawiya with the same chain. Hakim said, "Sahih in isnad." Abu Dawud narrated it (3597) through this same route, except that he abridged it and did not mention the debt in it.As for his statement, "Allah will settle him in the ridgha of khabal," the ridgha is thick mud and mire, its plural being ridgh and ridagh. Khabal originally means corruption, and it occurs in deeds, in bodies, and in minds. Its explanation has come in the hadith, that it is the discharge of the people of the Fire. See Nihaya (2/8, 215).
