Musnad Ahmad

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) was afflicted with hardship, he used to say: «لَا إِلٰهَ إِلَّا اللّٰهُ الْعَظِيمُ الْحَلِيمُ لَا إِلٰهَ إِلَّا اللّٰهُ أَنْتَ رَبُّ الْعَرْشِ الْعَظِيمِ لَا إِلٰهَ إِلَّا أَنْتَ رَبُّ السَّمَاوَاتِ وَرَبُّ الْأَرْضِ وَرَبُّ الْعَرْشِ الْكَرِيمِ» "There is no deity except Allah, the Most Great, the Most Forbearing. There is no deity except Allah, the Lord of the Mighty Throne. There is no deity except Allah, the Lord of the heavens and the earth and the Noble Throne."
