Khalaf ibn Hisham, Abu al-Rabi' al-Zahrani, and Qutaybah ibn Sa'id narrated to us, they said: Hammad—meaning Ibn Zayd—narrated to us. And Zuhayr ibn Harb and Ya'qub ibn Ibrahim narrated to me, they said: Isma'il narrated to us, both of them on the authority of Ayyub, on the authority of Abu Qilabah, on the authority of Anas, that the Messenger of Allah (peace be upon him) prayed the noon prayer in Medina as four rak'ahs, and prayed the afternoon prayer at Dhu al-Hulayfah as two rak'ahs.
