Illness is a blessing
Illness is also a great gift and there are many benefits from it although by looking at it may seem as if it is giving you difficulty, but in reality it is a source of rest and easiness and the illness that is of the body is actually a great source of medicine for the recovery of the soul.
What is real illness ?
The real illness is the illness of the soul and is something that should be feared and should be seen as a fatal illness. What should really happen is that a person should think of the illness or difficulty as a gift and accept it gladly, if not then at least have patience and understanding and hence by being impatient and complaining why lose the reward that has come your way and by being impatient the illness is not going to disappear but you will lose the reward and gain another problem and many people who are naive use wrong phrases and obtain sin and some in fact even say words of Kufr by blaming Allah of being cruel (may Allah protect us from this). These people destroy their world and afterlife due to these sorts of statement.
Sins are forgiven and reward is given for illness and difficulties
The Holy Prophet SallallahoAlaihiWasallam has stated that the difficulty that a Muslim suffers upto the extent that a thorn pricks them, then Allah Ta'ala forgives his sin [Bukhari, Muslim] and the Holy Prophet also states that if a Muslim is taken ill due to illness or suffers any other sort of difficulty then Allah drops his sins like a tree drops it's leaves [Sahih Bukhari, Sahih Muslim], and the Holy Prophet also states that Allah has set a grade for a Muslim and if they do not reach that grade due to poor actions then Allah tests them by either their health, goods or children and then gives them patience and then makes them reach their intended grade [Ahmad, Abu Da'wood] and he also states that on the day of judgement when Allah rewards themfor their patience the people who had rested and relaxed in this world will wish that only if scissors would have cut their skins and given them that sort of difficulty so that they could be collecting the reward [Tirmizi].
