This blessed book explains the meaning of true happiness, which is the ultimate goal of humans in this world.

Everyone is chasing happiness, but few are fully aware of what it is and where it comes from. Happiness is not a destination, but a journey that requires certain inner qualities and the right state of mind in order to experience and reap the rewards. It is not sold as a commodity and cannot be bought, but a person can only experience it by carefully improving his mindset, character, and by following a plan of action. For indeed, those who do not plan will not be able to achieve the desired results. The Messenger of Allah (peace and blessings of Allah be upon him) said: Those who are among us (destined to be) from people of happiness in the Hereafter do the deeds of people of happiness… [Sahih al-Bukhari, No. 4948].

Shaykh Nasir al-Saadi mentions twenty-one ways to achieve the goal of finding happiness, while driving away its opposites - sadness, grief and anxiety. Whoever follows these ways will find the path to happiness and success in this life and the next, In-sha-Allah.
