Allah calls on people to do what is easy. By adopting a morality that drives them into torment, some, however, choose what is difficult and thus wrong themselves. Although they can benefit from the beauties and blessings Allah creates for them in this world, in a full atmosphere of the love, sincerity and security which faith brings, still they spend their lives surrounded by concerns and anxieties of every type.
In fact the way to happiness is very easy and never too late for anybody. Allah shows people the solution in the verse, "Those who submit themselves completely to Allah and do good have grasped the Firmest Handhold. The end result of all affairs is with Allah" (Surah Luqman: 22). In another verse, Allah explains the solution to people's sorrows, afflictions and fears like this:
The angels descend on those who say, "Our Lord is Allah," and then go straight: "Do not fear and do not grieve but rejoice in the Garden you have been promised." (Surah Fussilat: 30)
People are responsible to follow the way Allah has shown. Those who demonstrate the morality approved by Allah will experience happiness, cheerfulness and joy in this world and the Hereafter and will receive eternal mercy. Whatever their causes for worry, all trouble and torment in their hearts will be removed and replaced by feelings of peace and security brought on by the manifestation of their faith in Allah.
They said "Glory be to You!
We have no knowledge except what You have taught us.
You are the All-Knowing, the All-Wise."
(Qur'an, 2: 32)
