The narration reported by ‘Ali ibn al-Hasan, from Muhammad ibn ‘Abd al-Hamid, from Abu Jamilah al-Mufaddal ibn Salih al-Asadi al-Nakhkhas, from Zayd al-Shahham, from Abu ‘Abdullah عليه السلام, states: Imam عليه السلام said: "If a menstruating woman wears a garment and keeps it on until she becomes pure, she should not pray in it until she washes it. However, if she has two garments, she may pray in the upper one. If she has no other garment, she should wash it when her menstruation begins, then wear it, and when she becomes pure, she may pray in it even if she has not washed it again."
