Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 44
وَ سَأَلَهُ مُحَمَّدُ بْنُ اَلنُّعْمَانِ اَلْأَحْوَلُ: فَقَالَ أَدْنَى مَا يَتَزَوَّجُ بِهِ اَلرَّجُلُ مُتْعَةً قَالَ "كَفٌّ مِنْ بُرٍّ يَقُولُ لَهَا زَوِّجِينِي نَفْسَكِ مُتْعَةً عَلَى كِتَابِ اَللَّهِ وَ سُنَّةِ نَبِيِّهِ نِكَاحاً غَيْرَ سِفَاحٍ عَلَى أَنْ لاَ أَرِثَكِ وَ لاَ تَرِثِينِي وَ لاَ أَطْلُبَ وَلَدَكِ إِلَى أَجَلٍ مُسَمًّى فَإِنْ بَدَا لِي زِدْتُكِ وَ زِدْتِنِي".
Muhammad ibn al-Nu'man al-Ahwal asked: "What is the minimum requirement for a man to marry a woman in Mut'ah?" Imam عليه السلام replied: "A handful of wheat. He should say to her: 'Marry me to yourself in Mut'ah according to the Book of Allah سبحانه وتعالى and the Sunnah of His Prophet, a marriage that is not fornication, with the condition that I will not inherit from you, nor will you inherit from me, and I will not seek a child from you, for a specified period. If we both wish, we can extend the period and increase the dowry mutually.'"
