All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alyhi wa sallam, is His slave and Messenger.
It is confirmed that the Prophet, sallallaahu ‘alayhi wa sallam , would glorify and praise Allaah before supplicating. This is mentioned in the books of remembrance like the Muslim’s Fortress, Al-Adhkaar Al-Nawawiyyah and so on.
It is reported that the Prophet, sallallaahu ‘alayhi wa sallam, would supplicate with the following supplication at times of distress and anguish: "None has the right to be worshipped except Allaah, the Exalted and Forbearing. None has the right to be worshipped except Allaah, Lord of the Magnificent Throne. None has the right to be worshipped except Allaah, Lord of the heavens, Lord of the earth and Lord of the Noble Throne." [Al-Bukhari and Muslim]
It is also reported that when he, sallallaahu ‘alayhi wa sallam, faced a difficulty he would say the following supplication: "O Ever-Living, O Self-Subsisting and Supporter of all. By Your mercy I seek assistance." [At-Tirmithi]
The Prophet, sallallaahu ‘alayhi wa sallam, also said: "The supplication Thu’n-Noon made when he was in the stomach of the fish was (what means): {None has the right to be worshipped but You (Allaah). Truly, I have been of the wrong-doers.}' If a man in anguish says it, Allaah will drive away his anguish and grief." [Al-Haakim]
The Prophet, sallallaahu ‘alayhi wa sallam, would also say: "Supplicate as much as you can with 'O Possessor of Majesty and Honor'".
Moreover, Imaam Ahmad and others reported on the authority of Ibn Mas'ood that he said, "The Prophet, sallallaahu ‘alayhi wa sallam, said: ‘O Allaah, I am Your slave, son of Your (male) slave, son of Your female slave, my forelock is in Your Hand, Your command over me is forever executed and Your decree over me is just. I ask You by every name belonging to You which You named Yourself with, revealed in Your Book, taught to any of Your creation, or You have preserved in the knowledge of the unseen with You, that You make the Quran the life of my heart and the light of my chest, and a departure for my sorrow and a release for my anxiety)' – (no sad person will say this) except Allaah will take away his sorrow and grief, and give him instead of that joy and happiness. People asked, ‘O Prophet of Allaah, do we have to learn these words' He replied: 'Anyone who heard them should learn them'".
Anas narrated that the Prophet, sallallaahu ‘alayhi wa sallam, heard a man saying, "O Allaah, I ask You; Praise be to You, there is no god but You, You have no partners or associates, You are the Beneficent, O Possessor of Majesty and Honour." and so the Prophet, sallallaahu alayhi wa sallam, told him: "Indeed you have asked Allaah with His Great Name by which if someone asks Him, He answers and responds to the call." [Ahmad, Abu Daawood]
As regards to asking for wealth, it is confirmed that the Prophet, sallallaahu ‘alayhi wa sallam, said to a person who asked him in this regard, "What do I say when I ask my Lord?” He, sallallaahu ‘alayhi wa sallam, said: “Say, ‘O Allaah, forgive me, have mercy upon me, enrich me, give me health, and grant me sustenance.’" Then he, sallallaahu ‘alayhi wa sallam, said: “These words are enough for you for this life and the Hereafter".
In another authentic narration reported by At-Tirmithi 'Ali narrated that a slave who wanted to free himself came to him and told him that he was unable to free himself by paying the due amount required by his master. 'Ali then said, "Shall I not teach you some words that the Prophet, sallallaahu ‘alayhi wa sallam, taught me if you have debts as big as the mountain of Subayr Allaah would help you pay your debts?” He then, said, say, “O Allaah, make what is lawful enough for me, as opposed to what is unlawful, and spare me by Your grace of the need of others".
It is also reported that the Prophet, sallallaahu ‘alayhi wa sallam, used to say as he got into bed: “My Lord, the Lord of the heavens, the earth and everything, who causes the grain and the fruit-stone to split, and who revealed the Torah, the Gospel and the Quran, I seek refuge with You from the evil of everything You hold by the forelock. You are the First before whom there was none, and You are the Last after whom there will be none. You are the Most High above whom there is none, and You are the Inward under whom there is none. Repay my debts and relieve my poverty.” [Al-Bukhari, Muslim, At-Tirmithi, Abu Daawood, and others]
Furthermore Anas narrated that the Prophet, sallallaahu ‘alayhi wa sallam, said to Mu'aath : "Shall I not teach you a supplication which, if you have debts as large as the mountain of Uhud, Allaah will help you repay them? O Mu'aath, say, ‘O Allaah, Possessor of the kingdom, You give the kingdom to whom You will. In Your Hand is the good, and indeed You are able to do all things. You are the Most Gracious, the Most Merciful in this life and in the Hereafter. You give the kingdom to whom You will and You take it from whom You will, forgive me with Your Mercy which will render me not in need of the mercy of others.’" [At-Tabraani]
Allaah Knows best.
