Supplication Subjected to Oppression:

Imam Musa bin Jafar Al Kazim said:

If a person, subjected to oppression, recites (the following) supplication, inshallah Allah will destroy the oppressor"

O He who equips me to cope with the hardships which have afflicted me, O He who helps me to take off the load of the sorrows which have burdened me, keeps an eye (which never sleeps) on me, make me competent to deal with (misfortunes) with the (help of) a strong reinforcement (from You) which cannot be knocked down. O He who owns the strongest strength, O He who owns the most majestic majesty, O He who owns the highest honour compared to which all that which has been created is low and humble, send blessings on Mohammad and on the children of Mohammad, make me competent to deal with the oppressor, and punish him for what he did to me.

According to Imam Musa bin Jafar al Kazim, to remove worries, recite any 100 verses of the holy Quran and at the end recite 3 times: O Allah, drive the misfortune away from me.
