Abu Bakr narrated to us, he said: Abu Abd al-Rahman al-Muqri narrated to us, from Sa'id ibn Abi Ayyub, he said: Khalid ibn Yazid al-Sadafi narrated to me, from his father, from Uqbah ibn Amir, that he used to command the menstruating woman at the time of prayer to perform ablution (wudu), sit in the courtyard of the mosque, remember Allah, proclaim His oneness (tahlil), and glorify Him (tasbih).
