Musnad Ahmad 27:244

Yahya narrated to us, from Ubaydullah, Nafi’ informed me, he said: I do not know it except from Abdullah: "That al-Abbas sought permission from the Messenger of Allah, may Allah bless him and grant him peace, to spend the nights of Mina in Makkah on account of the watering (of the pilgrims), and he granted him permission."
