What are the indicators in the Quran and Hadith that suggest someone has been led astray or has a hardened heart? Is it considered a sign of being astray if one reacts with anger, gives up easily, or questions the reasons behind things?
As someone who suffers from a lot of depression, i try my best to pray and build a relationship with God. Often times I try and remain patient and try to just take each day at a time. Then something happens and I am engulfed with anger, despair and frankly question why God has done something. This only lasts a while and then I'm back to some sense of peace and back to praying and trying to form a relationship with God.
So does the initial anger and loss of hope in those moments make me of those gone astray given I am questioning why God isn't allowing my situation to resolve? Or is this a natural and accepted human response and the peace afterwards is from God?
The state of the heart and the spirituality can change with the deeds and thoughts. When the heart submits to the will of Allah and be more involved in remembering Allah, then spiritually increases, and vice versa. Anger is a bad action which drives the person away from Allah and keeps him under the influence of Shaitaan. More remembering Allah increases the peace of mind and the spirituality. The believers who remember Allah sincerely not only enjoy the taste of remembering Him, but also gain more degrees in the spirituality and submission to the will of Allah (S.W.T). The remedy for any fault or anger or unwanted act is seeking forgiveness (Istighfaar).
