Musannaf Ibn Abi Shayba 3:5621

Isma'il ibn 'Ayyash narrated to us, from 'Abd al-'Aziz ibn 'Ubayd Allah, from Muhammad ibn 'Amr ibn 'Ata, who said: I saw al-Sa'ib ibn Khabbab smelling his garment, so I said to him, "What is that for, may Allah have mercy on you?" He said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say: "There is no ablution except from a wind (passing gas) or a sound."
