Maliks Muwatta Book 36, Hadith Number 7B.

Section : Judgement on a Deceased with a Debt against Him and a Debt for Him, and only One Witness.

Yahya said that Malik spoke about a man who died and had a debt owing to him and there was one witness, and some people had a debt against him and they had only one witness, and his heirs refused to take an oath on their rights with their witness. He said, “The creditors take an oath and take their rights. If there is anything left over, the heirs do not take any of it. That is because the oaths were offered to them before and they abandoned them, unless they say, ‘We did not know that our companion had extra,’ and it is known that they only abandoned the oaths because of that. I think that they should take an oath and take what remains after his debt.”
