Humaid ibn Abd al-Rahman narrated to us, from Hasan, from Abu Farwah, who said: Humaid ibn Abd al-Rahman narrated to us, from al-Wassafi, who said: I was with Umar ibn Abd al-Aziz, and he wrote to Abd al-Hamid: "Look at the women who are with you; let them not attend a Friday prayer nor a funeral, for they have no right to a Friday prayer nor a funeral."
