Allah ( Subhanahu wa ta'ala ) said : If you never felt pain or experienced problems, how would you know I'm the Healer?; If you never made a mistake, how would you know I'm the Forgiver?; If you were never hurt,how would you know I am the Comforter? If your life was perfect, then why would you need Me?
Hopefully we can be a better servant. Make a step. There's Hope. :)
