Musnad Ahmad 25:1288

Muhammad ibn Ja'far narrated to us, Sa'id narrated to us, from Qatadah; and Yazid ibn Harun said: Sa'id informed us, from Qatadah, who said: Abu al-'Aliyah al-Riyahi narrated to us, from Ibn 'Abbas, from the Messenger of Allah (may Allah bless him and grant him peace), that he used to say at times of distress: "There is no god but Allah, the Magnificent, the Forbearing. There is no god but Allah, Lord of the Magnificent Throne. There is no god but Allah, Lord of the heavens and the earth, and Lord of the Noble Throne." Yazid said: "Lord of the seven heavens, and Lord of the Noble Throne."
