Musannaf Ibn Abi Shayba 14:170

Abu Bakr narrated to us, he said: Yahya ibn Abi Bukayr narrated to us, he said: Zuhayr ibn Muhammad narrated to us, from Yazid ibn Khusayfah, from ‘Amr ibn ‘Abd Allah ibn Ka‘b, from Nafi‘, from ‘Uthman ibn Abi al-‘As al-Thaqafi, who said: I came to the Messenger of Allah (may Allah bless him and grant him peace) while I had a pain that had almost incapacitated me. The Messenger of Allah (may Allah bless him and grant him peace) said to me: "Place your right hand upon it, then say: 'In the name of Allah, I seek refuge in the might of Allah and His power from the evil of what I feel,' seven times." I did that, and Allah healed me.
