Musannaf Ibn Abi Shayba 3:3633

Ali bin Hashim narrated to us, he said: I asked Ibn Abi Layla and said: "The Banu Salama wanted to move near the mosque." So he mentioned from Abu al-Zubayr, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "For indeed, in every step there is a good deed."
