The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Abu al-Qasim Ja'far ibn Muhammad, from Muhammad ibn Ya'qub, from Ali ibn Ibrahim, from his father, from Ibn Abi Umayr, from Ammar ibn Marwan, from Zayd al-Shahham, who said: I heard Abu Abdullah عليه السلام say: "It is recommended for a menstruating woman to perform ablution (wudu) at the time of every prayer, then face the qiblah and remember Allah سبحانه وتعالى, the Exalted, for the duration she would normally spend in prayer."
