What is the most potent supplication one can make when one's heart feels constricted?
Removing hardship and opening the breast of man are in the Hand of Allah Almighty Alone.If you are afflicted with a hardship,if you feel yourself hampered or inhibited,turn to Allah Almighty and ask Him to remove your hardship.Do what the Messenger of Allah `sallAllahu alaihi wa sallam used to do when hardship befell him,he would turn prayer and he used to say when afflicted:
لَا إلَهَ إِلَّا اللَّهُ الْعَظـيمُ الْحَلِـيمْ، لَا إِلَهَ إِلَّا اللَّهُ رَبُّ العَـرْشِ العَظِيـمِ، لَا إِلَـهَ إِلَّا اللَّهْ رَبُّ السَّمَـوّاتِ ورّبُّ الأَرْضِ ورَبُّ العَرْشِ الكَـريم
La ilaha illalllahul adhimul halim. La ilaha illallahu,rabbul arshil adhim. La ilaha illallahu, rabbus samawati wa rabbul ardi wa rabbul arshil karim.
"None has the right to be worshipped except Allah,the Magnificent,the Foebearing.None has the right to be worshipped except Allah,Lord of the magnificent throne.None has the right to be worshipped except Allah,Lord of the heavens,Lord of the Earth and Lord of the noble throne."
