Musannaf Ibn Abi Shayba 17:1339

Isma'il ibn 'Ulayyah narrated to us, from Hajjaj al-Sawwaf, he said: Yahya ibn Abi Kathir narrated to me, he said: It reached me that the Messenger of Allah, may Allah bless him and grant him peace, used to say: "If one of you passes by a leaning target or a leaning wall, let him quicken his pace and ask Allah for well-being (al-mu'afah)."
