Isma'il ibn 'Abd Allah ibn Khalid al-Qurashi narrated to us, 'Ubayd Allah ibn 'Amr narrated to us, from Ayyub, from Abu Qilabah and Humayd ibn Hilal, from Anas, who said: I was riding behind Abu Talhah, and his knee was touching the knee of the Prophet, may Allah bless him and grant him peace. They were shouting out both Hajj and 'Umrah together.
