And Muhammad ibn Hatim and Ubaydullah ibn Sa'id narrated to me, both saying: Yahya ibn Sa'id narrated to us, from Hajjaj al-Sawwaf, who said: Yahya ibn Abi Kathir narrated to us, from Abu Salama and Abdullah ibn Abi Qatada, from Abu Qatada, who said: The Messenger of Allah, peace and blessings be upon him, said: "When the prayer is established, do not stand until you see me." And Ibn Hatim said: "When it is established or the call is made."
