٤- عَلِيُّ بْنُ مُحَمَّدٍ عَنْ صَالِحِ بْنِ أَبِي حَمَّادٍ عَنِ ابْنِ سِنَانٍ عَنِ الْمُفَضَّلِ بْنِ عُمَرَ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) يَقُولُ فِي الْمُتْعَةِ دَعُوهَا أَمَا يَسْتَحْيِي أَحَدُكُمْ أَنْ يُرَى فِي مَوْضِعِ الْعَوْرَةِ فَيُحْمَلَ ذَلِكَ عَلَى صَالِحِي إِخْوَانِهِ وَأَصْحَابِهِ. 
4. Ali ibn Muhammad has narrated from Salih ibn abu Hammad from ibn Sinan from al-Mufaddal ibn ‘Umar who has said the following: “I once heard abu ‘Abd Allah , saying about al-Mut‘ah (advantageous marriage), ‘Stay away from it. Do you not feel ashamed of being seen in a place for which your virtuous brothers in belief and friends feel embarrassed?”’
