Translation:

"From the sign of completeness of a servant's intelligence and knowledge is that he knows if Allaah has afflicted him with some evil, and that none can remove it except Him سبحانه وتعالى.

And if He سبحانه وتعالى  blessed him with a favor, then none can provide for him with the like except Him عزوجل."

 

Ibnul Qayyim رحمه الله
