What is an invocation? Or Dua? In a real sense, invocation is a request that originates from the bottom of our heart and goes towards Almighty Allah. The Kind Lord is always willing, ready and happy to listen to us and accept prayers from anyone at any time. Muslims are ordered to turn to Allah in case of any problem, difficulty or trouble. That s why; Islam has provided us a handsome number of invocations to recite on different occasions.
