[20].Surah Taha [Tâ-Hâ]:Ayat 5-6

Ayat 5. The Most Beneficent (Allah) Istawâ (rose over) the (Mighty) Throne (in a manner that suits His Majesty).

Ayat 6. To Him belongs all that is in the heavens and all that is on the earth, and all that is between them, and all that is under the soil. 

[Tafseer] ((Allah)) Most Gracious is firmly established on the throne (of authority). If things seem to be wrong in our imperfect vision on this earth, we must remember that Allah, Who encompasses all Creation and sits on the throne of Grace and Mercy, is in command, and our Faith tells us that all must be right. Allah's authority is not like an authority on earth, which may be questioned, or which may not last. His authority is "firmly established". To Him belongs what is in the heavens and on earth, and all between them, and all beneath the soil. An exhaustive definition of everything we can conceive of—what is in the heavens, on the earth. or between, or within the bowls of the earth.   

Hazrat Ibn `Abbas (May Allah be pleased with them) said: The Messenger of Allah [SAWW](PBUH) used to say when he was in distress: "La ilaha illallahul-Azimul-Halim. La ilaha illallahu Rabbul-`Arshil-`Azim. La ilaha illallahu Rabbus-samawati, wa Rabbul-ardi, wa Rabbul-`Arshil-Karim. (None has the right to be worshipped but Allah the Incomparably Great, the Compassionate. None has the right to be worshipped but Allah the Rubb of the Mighty Throne. None has the right to be worshipped but Allah the Rubb of the heavens, the Rubb of the earth, and the Rubb of the Honourable Throne).''

[Al-Bukhari Book 08, Chapter 75, Hadith # 357] 

Lesson : as mentioned above in Surah Taha Ayat 05."The Most Beneficent (Allah) Istawâ (rose over) the (Mighty) Throne (in a manner that suits His Majesty)" The only medicine in a time of distress is the remembrance of Allah Whose Help alone should be sought. This Dua contains words which glorify Allah and exalt Him far above all else. It is desirable to recite these words when one is in distress as this is exactly what the Prophet (PBUH) used to recite in such situations.
