It is a life nature that people encounter successive troubles and sorrows which cause them severe anguish. This is described in the Quranic verse: (We have certainly created man into hardship), Al-Balad, 4.

People might resort to different ways on seeking solution to their troubles; however, the prophet advised us to resort to Allah, as He alone possesses relief. Allah says: (Say, "It is Allah who saves you from it and from every distress), Al-An`am, 64.

Bukhari narrated on the authority of ibn `Abbas that the Prophet used to say in cases of anguish: (There is no deity but Allah, the Knowing; the forbearing. There is no deity but Allah, the Lord of the Great Throne. There is no deity but Allah,  the Lord of the seven heavens and Lord of earth; the lord of the Noble Throne.?

Through this invocation; the Prophet (PBUH) notifies us that Allah is the dominant over all things, and He is the lord of the heavens and earth.
