"Let's say my boss is very strict and gives me a lot of work to within a short timespan.
I can't quit the job or refuse to do the hard work (otherwise he will fire me).
But inside I start to hate him at times, or not even hate, more frustration.
Because of that I get rebellious thoughts such as that I refuse to work and yell at my boss to do it himself. "
Do you mean something like this? That is a rebellious thought though, but it is not (neccesarily) unpleasant.
Or do you mean having thoughts such as beating the hell out of your boss. Breaking every bone in his body. Making him eat dog poo. cutting off his toes and fingers?
I think even the latter would not be intrusive. Because you are frustrated by your boss, hence you get these thoughts to release your frustrations.
Jumping off my balcony..hurting my child(used to have those 1month post delivery..thank God now I dont)..killing my husband lol..get divorce..leave the house in the middle of the night and never return..to hang myself..fearing a car accident..hearing the news of someone's death..some are related to religion..etc
Now I am being honest so dont judge me..but these are rare and I am able to brush them off my mind easily and say Astaghfaar..ask for forgiveness from Allah and engage myself in something else..
Once I heard someone say that sahaba came to the Prophet(saw) and told him that they get very bad thoughts which they cant share with anyone since they are so hideous..Prophet said that this is the sign that Iman is present inside u..
Thats the mafoom that I heard and I am not so sure so dont quote me:)
It becomes a problem when somebody fears that he will actually act upon these thoughts.
Does anyone ever fear that?
No.I know I won't ever act upon my thoughts.
I ONLY get them during salat, it can be so challenging to develop khushoo. I have been getting them since I was like 13, I have tried everything but they never fully go away. I really just ignore them, ask Allah swt for forgiveness and try to carry out my salat to the best I can. If I am not praying for whatever reasons, I don't get them.
