A man had an argument with his wife and said, “I am going to make your life miserable.” The wife calmly replied, “You cannot do that.” He said, “Why not?” She said, “If happiness were to be found in money or jewelery, you could deprive me of it and take it away from me, but it is nothing over which you or any other person has any control. I find my happiness in my faith, and my faith is in my heart, and no one has any power over it except my Lord.”
This is true happiness, the happiness of faith, and no one can feel this happiness except the one whose mind, heart and soul are filled with the love of Allah. The one who truly has control over happiness is the One True God, so seek happiness from Him by worshiping and obeying Him.
The only way to find happiness is by learning the true religion with which the Messenger of Allah (Blessings and Peace be upon him) was sent. Once a person finds this way, it will not matter if he sleeps in a hut or by the side of the road, and he will be content with a piece of bread, and he will be the happiest person in the world. But whoever goes astray from His path will find that his whole life is filled with grief, his wealth is deprivation, his efforts are loss and his end will be humiliation. May Allah SWT guide us and keep us firm on His path, Ameen.
