Chapter on What is Permissible and Impermissible to Pray in - of Clothing and Place

Muhammad ibn Mas‘ud Al-‘Ayyashi, from Ja‘far ibn Muhammad, who said: Al-‘Amraki narrated to me from Ali ibn Ja‘far, from his brother (Imam) Musa عليه السلام, peace be upon him, who said: I asked Imam عليه السلام about an imam (of prayer) who was leading the Dhuhr prayer, and a woman stood beside him praying, thinking it was the ‘Asr prayer, does that invalidate the prayer of the group? And what is the ruling for the woman in her prayer with them, given that she had already prayed Dhuhr? Imam عليه السلام said: "It does not invalidate the prayer of the congregation, but the woman must repeat her prayer."
