Assalamualaikum
In life there so much thing that you can control. Especially how you want to handled situation that effect you life. In Islam you are asked to believe to 6 fundamental of iman and one of it is Qada' and Qadar which translate as the faith good and bad , destiny that Allah swt has decreed.
For that I, as a Muslim bound to believe that all have been faithed as it is. I have fought for many-many years just to find happiness. But again I just have this problem of not having it yet totally. I do also believe in anything bad or good there will be a hikmah~translated as the power of Allah giving good in any bad or good things happening in life. For that I am thankful.
Just sharing.
Wassalam.
