Sahih al-Bukhari, Book 97, Hadith 58 (In-Book) ⓘ
Narrated Ibn `Abbas: Allah's Messenger used to say at the time of difficulty, "None has the right to be worshipped but Allah, the Majestic, the Most Forbearing. None has the right to be worshipped but Allah, the Lord of the Tremendous Throne. None has the right to be worshipped but Allah, the Lord of the Heavens and the Lord of the Honourable Throne. (See Hadith No. 357, Vol. 8)
حَدَّثَنَا عَبْدُ الأَعْلَى بْنُ حَمَّادٍ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَبِي الْعَالِيَةِ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم كَانَ يَدْعُو بِهِنَّ عِنْدَ الْكَرْبِ " لاَ إِلَهَ إِلاَّ اللَّهُ الْعَظِيمُ الْحَلِيمُ، لاَ إِلَهَ إِلاَّ اللَّهُ رَبُّ الْعَرْشِ الْعَظِيمِ، لاَ إِلَهَ إِلاَّ اللَّهُ رَبُّ السَّمَوَاتِ وَرَبُّ الْعَرْشِ الْكَرِيمِ " .
