Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 11
وَقَالَ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: «فَرَضَ اَللَّهُ عَزَّ وَ جَلَّ عَلَى اَلنَّاسِ فِي اَلْوُضُوءِ أَنْ تَبْدَأَ اَلْمَرْأَةُ بِبَاطِنِ ذِرَاعِهَا وَ اَلرَّجُلُ بِظَاهِرِ اَلذِّرَاعِ.
Imam Ali ibn Musa Ar-Ridha عليه السلام said: "Allah سبحانه وتعالى, Mighty and Majestic, has prescribed for people in wudu that a woman should begin with the inner part of her arm, while a man should begin with the outer part of his arm”.
