Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 55
وَ رَوَى عِيصُ بْنُ اَلْقَاسِمِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلرَّجُلِ يُصَلِّي فِي إِزَارِ اَلْمَرْأَةِ وَ فِي ثَوْبِهَا وَ يَعْتَمُّ بِخِمَارِهَا قَالَ «إِذَا كَانَتْ مَأْمُونَةً فَلاَ بَأْسَ.
Iyas ibn al-Qasim narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام about a man who prays in a woman's izar (waistcloth), in her garment, and uses her khimar (headcover) as a turban. Imam عليه السلام said: "If She is trustworthy (māʾmūnah), there is no harm."
