How to overcome disappointments? I always face hard times and never get moments of happiness. Is it because of my sins? What does a believer do when faced with such trying times and disappointments all his life?
The believer is subjected to tests and Allaah’s testing him by means of things that may harm or hurt him brings two great benefits. The first benefit is that Allaah tests this man with regard to 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 Allaah, 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 Allaah suffered a cut or wound in 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 Allaah and submits to Him completely. This is one benefit.
With regard to the second benefit, Allaah highly praises those who are patient and says that He is with them and that He will give them reward without measure. Patience is a high status which can only be attained by those who are tested with things that they bear patiently. If he bears them patiently, he attains this high status which brings great reward. So when Allaah tests the believers with things that hurt them, that is so that they may attain the status of those who are patient. Hence the Messenger (peace and blessings of Allaah be upon him), who was the greatest of all people in faith, piety and fear of Allaah, suffered twice the pain of an ordinary man when he fell sick, and he (peace and blessings of Allaah be upon him) suffered greatly at the time of death, so that he might fully attain the status of one who is patient, for he (peace and blessings of Allaah be upon him) was the most patient of those who are patient. Hence the wisdom behind Allaah’s testing of the believer with such calamities becomes clear.
With regard to His giving the sinners, evildoers, immoral people and disbelievers good health and plentiful provision, this is in order to let them get carried away (with their sin, and then punish them severely later on).
It was narrated that the Prophet (ﷺ) said:
“This world is a prison for the believer and a paradise for the disbelievers. They are given these good things so that they have their good things sooner, in this world, and on the Day of Resurrection they will get what they deserve of punishment. 
“On the Day when those who disbelieve (in the Oneness of Allaah Islamic Monotheism) will be exposed to the Fire (it will be said): “You received your good things in the life of the world, and you took your pleasure therein. Now this Day you shall be recompensed with a torment of humiliation, because you were arrogant in the land without a right, and because you used to rebel against Allaah’s Command (disobey Allaah)”
The point is that this world is for the disbelievers to get carried away in, then when they move to the Hereafter and leave the life of this world in which they found pleasure, they will encounter torment – we seek refuge with Allaah. The punishment will be so much harder for them because they will suffer greatly, and because at the same time they will have lost the delights and luxuries of this world which they loved so much.
There is a third benefit which we may add to the first two, which the believer will get from sickness and problems, for the believer will move to a realm that is better than this world, for he will move from something that hurts him and causes him pain to something that will bring him happiness and joy. So his joy at the delight to which he has come will be multiplied, because he has attained joy, and the pain and difficulties that he was facing will have ceased.
