Chapter on Temporary Marriage (Mutʿah)
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 44
وَ رَوَى مُوسَى بْنُ بَكْرٍ عَنْ زُرَارَةَ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ يَقُولُ: "عِدَّةُ اَلْمُتْعَةِ خَمْسَةٌ وَ أَرْبَعُونَ يَوْماً" كَأَنِّي أَنْظُرُ إِلَى أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ يَعْقِدُ بِيَدِهِ خَمْسَةً وَ أَرْبَعِينَ يَوْماً "فَإِذَا جَاءَ اَلْأَجَلُ كَانَتْ فُرْقَةً بِغَيْرِ طَلاَقٍ".
Musa ibn Bakr narrated from Zurara, who said: I heard Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام saying: "The waiting period ('Iddah) for Mut'ah (temporary marriage) is forty-five days." Imam عليه السلام then demonstrated by holding up his hand and showing forty-five days. "When the specified term ends, the separation occurs without the need for divorce."
