1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Ali ibn Yaqtin who has said the following: “I once asked abu al-Hassan, Musa عليه السلام, about al-Mut‘ah (advantageous marriage). He (the Imam) said, ‘What do you have to do with it when Allah has made you free of need for it?’ I then said, ‘I only wanted to know about it.’ He (the Imam) said, ‘It is in the book of Ali عليه السلام .’ I then asked, ‘Can we extend and they women extend (the time)?’ He (the Imam) said, ‘What else makes him happy?”’
