Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 19
وَ فِي خَبَرٍ آخَرَ: "ثُمَّ يَقُومُ اَلرَّجُلُ فَيَحْلِفُ أَرْبَعَ مَرَّاتٍ بِاللَّهِ "إِنَّهُ لَمِنَ اَلصّٰادِقِينَ" فِيمَا رَمَاهَا بِهِ ثُمَّ يَقُولُ اَلْإِمَامُ لَهُ اِتَّقِ اَللَّهَ فَإِنَّ لَعْنَةَ اَللَّهِ شَدِيدَةٌ ثُمَّ يَقُولُ اَلرَّجُلُ لَعْنَةُ اَللَّهِ عَلَيْهِ "إِنْ كٰانَ مِنَ اَلْكٰاذِبِينَ" فِيمَا رَمَاهَا بِهِ ثُمَّ تَقُومُ اَلْمَرْأَةُ فَتَحْلِفُ أَرْبَعَ مَرَّاتٍ بِاللَّهِ "إِنَّهُ لَمِنَ اَلْكٰاذِبِينَ" فِيمَا رَمَاهَا بِهِ ثُمَّ يَقُولُ لَهَا اَلْإِمَامُ اِتَّقِي اَللَّهَ فَإِنَّ غَضَبَ اَللَّهِ شَدِيدٌ ثُمَّ تَقُولُ اَلْمَرْأَةُ غَضَبُ "اَللّٰهِ عَلَيْهٰا إِنْ كٰانَ مِنَ اَلصّٰادِقِينَ" فِيمَا رَمَاهَا بِهِ ".
In another narration, it is described that the man stands and swears four times by Allah سبحانه وتعالى, saying: "Indeed, I am of the truthful in what I have accused her of." Then the Imam says to him, "Fear Allah سبحانه وتعالى, for the curse of Allah سبحانه وتعالى is severe." The man then says, "May the curse of Allah سبحانه وتعالى be upon me if I am among the liars in what I have accused her of." Then the woman stands and swears four times by Allah سبحانه وتعالى, saying, "Indeed, he is among the liars in what he has accused me of." The Imam then says to her, "Fear Allah سبحانه وتعالى, for the anger of Allah سبحانه وتعالى is severe." She then says, "May the anger of Allah سبحانه وتعالى be upon me if he is among the truthful in what he has accused me of."
