I said to Ibn Umar, "What about a man who accuses his wife of adultery?"He replied, "The Messenger of Allah ﷺ separated the two siblings of Banu Ajlan. He said, 'Allah knows that one of you is lying. Will either of you repent?' He said this to them three times, but they refused, so he separated them."Ayub said that Amr bin Dinar said, "There is something in this hadith that I do not see you narrating."He said, the man asked, "What about my wealth?"He replied, "You have no claim to your wealth. If you were truthful, then you have already consummated the marriage with her. And if you were lying, then it is even further removed from you."
أخبرنا زياد بن أيوب قال حدثنا ابن علية عن أيوب
قلت لابن عمر رجل قذف امرأته قال فرق رسول الله ﷺ بين أخوي بني العجلان وقال الله يعلم إن أحدكما كاذب فهل منكما تائب قال لهما ثلاثا فأبيا ففرق بينهما قال أيوب وقال عمرو بن دينار إن في هذا الحديث شيئا لا أراك تحدث به قال قال الرجل مالي قال لا مال لك إن كنت صادقا فقد دخلت بها وإن كنت كاذبا فهي أبعد منك
