Musnad Ahmad 5:139

Rawh narrated to us, Usamah ibn Zayd narrated to us, from Muhammad ibn Ka'b al-Qurazi, from Abdullah ibn Shaddad ibn al-Had, from Abdullah ibn Ja'far, from Ali ibn Abi Talib, who said: The Messenger of Allah (peace and blessings of Allah be upon him) taught me that if distress befalls me, I should say: "There is no god but Allah, the Forbearing, the Generous. Glory be to Allah, and blessed is Allah, the Lord of the Great Throne, and praise be to Allah, the Lord of the worlds."
