The believer is subjected to Tests and Allah’s Testing him through things that may harm or hurt him brings two great benefits.
The First benefit is that Allah tests this man concerning his Faith, to see whether his Faith is sincere or shaky. The Believer whose Faith is sincere will patiently accept the will and decree of Allah and will seek reward From Him. In this case, the matter becomes bearable For him.
It was narrated that one of the Female worshippers of Allah suffered a cut or wound on her Finger, but she did not complain about the pain or show any sign of distress. She was asked about that and she said: The sweetness of its reward makes me Forget the bitterness of bearing it. The believer seeks reward From Allah and submits to Him completely.
