Allah is the source of true happiness. He is Ever-Forgiving and Most Merciful, and has equipped the world with all manner of wonders for everyone to enjoy. People can find lasting joy, tranquility, and happiness through faith in Allah and living their lives in accordance with religious morality. In order to experience the blessings of life and appreciate the beauty of what Allah has created, they must form a relationship with Him that is based on true faith and submission to the Qur'an.
Without this, they will not be able to find the true happiness they seek. Allah has provided us with the Qur'an as a mercy to guide us towards a life of happiness. We must strive to live in accordance with Allah's wishes and the nature He has created us with to be truly happy. Those who stray off the path will find themselves in despair, pessimism and hopelessness, and they will be punished in the afterlife. We can protect ourselves from these punishments by following the teachings of Allah, having sincere faith and trusting in Him.
