Sunan an-Nasa'i, Volume 4, Book 27, Hadith 3505 (DarusSalam) ⓘ

It was narrated from Ayyub, that Sa'eed bin Jubair said: "I said to Ibn 'Umar: 'A man accused his wife.' He said: 'The Messenger of Allah separated the couple from Banu 'Ajlan and said: Allah knows that one of you is lying, so will either of you repent? He said that to them three times and they did not respond, then he separated them.'" (One of the narrators) Ayyub said: "Amr bin Dinar said: 'In this Hadith there is something that I think you are not narrating.' He said: 'The man said: My wealth. He said: You are not entitled to any wealth. If you are telling the truth, you have consummated the marriage with her, and if you are lying then you are even less entitled to it.'"
