The Prophet Muhammad would recite phrases during times of difficulty to seek help from Allah. He would say that none has the right to be worshipped except Allah, who is Majestic and Forbearing. He would also say that none has the right to be worshipped except Allah, who is the Lord of the Tremendous Throne and the Lord of the Heavens and the Honourable Throne.

2.  Narrated Ibn Abbas: Allah's Apostle 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.
(Sahih Al-Bukhari, Vol. 9, Hadith 526)
