لَا إِلَهَ إِلَّا اللَّهُ الْحَلِيمُ الْكَرِيمُ، لَا إِلَهَ إِلَّا اللَّهُ الْعَلِيُّ الْعَظِيمُ، سُبْحَانَ اللَّهِ رَبِّ السَّمَوَاتِ السَّبْعِ وَرَبِّ الْعَرْشِ الْعَظِيمِ، اَلْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِيْنَ

Laa ilaha illallaahul halimul karim, laa ilaaha illallaahul ‘aliyyul ‘azim, subhaanallaahi rabbis samawaatis sab’i wa rabbil ‘arshil ‘azim, alhamdu lillaahi rabbil ‘aalamin

There is no true God but Allah the Most Patient, the Most Honorable. There is no true God but Allah the Most Exalted, the Most High. I am proclaiming the holiness of the Lord of the seven heavens and the Lord of the glorious throne. All praise is due to Allah, the Lord of the worlds. ‘Narrated from Ali bin Abi Talib (RA), will I not teach you some sentences which if you say you will be forgiven even though you are forgiven (He then told the above sentences)
