Narrated Ibn `Abbas (RA): Allah's Messenger (ﷺ) used to say at a time of distress:
لَا إِلَهَ إِلَّا اللَّهُ الْعَظِيْمُ الْحَلِيمُ، لَا إِلَهَ إِلَّا اللَّهُ رَبُّ الْعَرْشِ الْعَظِيمِ لَا إِلَهَ إِلَّا اللَّهُ رَبُّ السَّمَاوَاتِ وَرَبُّ الْأَرْضِ وَرَبُّ الْعَرْشِ الْكَرِيمِ
لَا اِلٰهَ اِلَّا اللّٰهُ الْعَظِيْمُ الْحَلِيْمُ، لَا اِلٰهَ اِلَّا اللّٰهُ رَبُّ الْعَرْشِ الْعَظِيْمِ لَا اِلٰهَ اِلَّا اللّٰهُ رَبُّ السَّمَاوَاتِ وَرَبُّ الْاَرْضِ وَرَبُّ الْعَرْشِ الْكَرِيْمِ
Laa ilaaha illallahul 'azimul halim Laa ilaaha illaallahu Rabbul 'arshil-'azim, Laa ilaaha illaallahu Rabbu-s-samaawaati wa Rabbul ardi, wa Rabbul 'arsh-il-Karim
There is none worthy of worship but Allah the Mighty, the Forbearing. There is none worthy of worship but Allah, Lord of the Magnificent Throne. There is none worthy of worship but Allah, Lord of the heavens and Lord of the earth, and Lord of the Noble Throne.
