لَا إِلٰهَ إِلَّا اللّٰهُ الْعَظِيمُ الْحَلِيمُ، لَا إِلٰهَ إِلَّا اللّٰهُ رَبُّ الْعَرْشِ الْعَظِيمِ، لَا إِلٰهَ إِلَّا اللّٰهُ رَبُّ السَّمَاوَاتِ وَرَبُّ الْأَرْضِ، وَرَبُّ الْعَرْشِ الْكَرِيمِ Translation: There is no god but Allah, the Most Great, the Most Forbearing. There is no god but Allah, the Lord of the Mighty Throne. There is no god but Allah, the Lord of the heavens and the Lord of the earth, and the Lord of the Noble Throne. This dua is mentioned in Sahih al-Bukhari and Sahih Muslim, and it was recited by the Prophet Muhammad (peace be upon him) in times of distress
