Wazefas

Re: Wazefas

Ok so what i have learnt is the scholars prescribe you a wazefa for accomplishment of so and so task as reading it will be more effective, ok this much i can digest.
but what i find problem in digesting is when scholars tell a person that his so and so task is pending or not been done because he has evil effects on him of some “bad jinns” or alike and that they are putting hurdles to him and if he do the wazefa then the evil effects will finish and he can accomplish what he is striving for.
i mean ok i understand that there are evil people that exist and there are evil jinns that exist but how can they be so powerful that they can create hurdles in someone’s life.? i mean whatever happens in your life happens with the will of ALLAH so how can some evil jinn take charge of the events in your life? But some Scholars say it can happen and then they give you wazefas to fight that evil.?
