Even the faithful vary in their fear of Allah and the faith in Him which they hold in their hearts. These individuals may live with their faith, but at moments when their interests are challenged or when they are faced with problems, may also demonstrate the behavior of unbelievers instead of behaving in accordance with the Qur'an. 
The people concerned may conform to most provisions of the Qur'an and behave like believers throughout a large portion of their lives. On certain matters, however, they may not like to be aware that according to the Qur'an, they are in the wrong. 
For a person who suffers trouble and sorrow throughout his life, the solution is simple. Every person with faith in Allah and every believer who conforms to the Qur'an must approach the Book with greater sincerity and must be protected from any kind of act or thought that runs counter to the behavior of the faithful described in its verses. He should not regard the truths contained in the Qur'an as theoretical, but should apply them in practice in his life and feel and experience them at all times.
He must not forget that Allah encompasses everything and that He knows all the secret emotions inside a person, including concealed insincerity. A Muslim should not regard simply performing religious observances as sufficient and view the insincerity inside himself as insignificant. 
All living creatures bow to Allah and act according to His instructions. Muslims should live in submission to their destiny without forgetting these truths and knowing that in every event, there is a goodness and a blessing. When a person arrives at awareness of these truths, he will see a different, beautiful life begin for him. When we speak of «living a beautiful life,» you should not take this to mean that people will experience no difficulty, for this world is a place where everyone is tested, and a person will be tested by various events until the end of his life.
As Allah tells us in the verses of the Qur'an, everyone will suffer difficulties and problems. Thinking positively about events and submitting to the will of Allah, the Possessor of boundless knowledge, brings lasting and genuine happiness.
