Chapter on Oaths, Vows, and Expiations
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 38
وَ قَالَ عَلَيْهِ اَلسَّلاَمُ: "كُلُّ يَمِينٍ لاَ يُرَادُ بِهَا وَجْهُ اَللَّهِ عَزَّ وَ جَلَّ فَلَيْسَ بِشَيْءٍ، فِي طَلاَقٍ أَوْ عِتْقٍ ".
Imam عليه السلام said: "Any oath that is not intended for the sake of Allah سبحانه وتعالى, the Almighty and Glorious, is of no consequence, whether it pertains to divorce or emancipation."
