Sunan Ibn Majah Book 34, Hadith 56
“The Messenger of Allah (ﷺ) taught me some words to say at times of distress: Allah! Allahu Rabbi la ushriku bihi shay’an (Allah, Allah is my Lord, I do not associate anything with Him).”
“There is no person who goes to bed in a state of purity, then wakes up at night, and asks Allah for something in this world or the Hereafter, but it will be given to him.”
“La ilaha illallahul-Halimul-Karim, Subhan-Allahi Rabbil-‘Arshil-‘Azim, Subhan-Allahi Rabbil-samawatis-sab’i wa Rabbil-‘Arshil-Azim (None has the right to be worshipped but Allah, the Forbearing, the Most Generous; glory is to Allah the Lord of the Mighty Throne; glory is to Allah, the Lord of the seven heavens and the Lord of the Magnificent Throne).” Waki’ said with each wording La ilaha illallahu (none has the right to be worshipped but Allah) is to be included.
