Supplication to remove suffering

Q 11: What is the best Du`a' (supplication) that removes suffering?

A: It is Allah (Exalted be He) Alone Who can relieve a person's distress, drive away their grief, and delight their heart. Accordingly, if you are afflicted by any of the foregoing; you have to hasten to seek help from Allah (Exalted be He) Alone. You have to ask Him (Exalted be He) to remove your difficulty. You have to do as the Prophet (peace be upon him) used to do whenever he was faced by a severe hardship, i.e. to hurry to perform voluntary Salah (Prayer). Moreover, the Prophet (peace be upon him) taught us to say whenever we are afflicted by any distress: La ilaha illa Allah Al-`Azhim Al-Halim, la ilaha illa Allah rabbul-`Arshi Al-`Azhim, la ilaha illa Allah, rabbul-Samawati wa rabbul-Ardi wa rabbul-`Arshi Al-Karim. (None has the right to be worshipped except Allah, the Great and the All-Forbearing. None has the right to be worshipped except Allah who is the Lord of the Great Throne. None has the right to be worshipped except Allah, the Lord of the heavens and the earth and the Lord of the noble Throne.) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
