Mukhtasar Bukhari

Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Prophet Muhammad (peace and blessings be upon him) said to the man and woman who performed li'an: "Allah, the Exalted, will take account from both of you. Surely one of you is lying. You both must separate." The husband said, "What about my wealth (that I gave her)?" The Prophet (peace and blessings be upon him) said: "If you are truthful, even then you have had intercourse with her, so that wealth is gone in exchange for that. And if you have falsely accused the woman (of adultery), then you truly do not deserve to get it."
