Laughing moderately can act as a cure or as therapy for depression and sadness. It has a strong influence on keeping the soul light and the heart clear. Abu Darda’ (may Allah be pleased with him) said, “I make it a practice to laugh in order to give rest and comfort to my heart. And the noblest of people, Muhammad (bpuh), would laugh, sometimes until his molars became visible.”
Laughing is an efficacious way to achieve comfort and light-heartedness. The Prophet (Blessings and Peace be upon him) said:
“And if you smile in the face of your brother, then that is a form of charity.” (At-Tirmidhi)
The Prophet (Blessings and Peace be upon him) said:
“Do not disparage (underestimate) any good deed (no matter how small it is), even if that deed was to meet your brother with a friendly countenance.” (Sahih Muslim).
Nothing causes the soul or the face to frown more often and with more intensity than despondency. If you want to be a smiling person, wage war with despondency and hopelessness. The door to opportunity is always open to you and to others, and so is the door to success. So indoctrinate your mind with hopes of prosperity in the future.
The smiling soul sees difficulties, and loves to surmount them. When it sees problems, it smiles, reveling in the opportunity to solve and overcome them. The frowning soul, when faced with a problem, magnifies it and belittles its own determination, while spending all its time justifying. It loves success in life, but is not willing to pay its price. On every path, it sees a grinning lion. It waits only for gold to shower down upon it, or to chance upon some treasure in the ground.
Difficult things in life are only relative, for everything is difficult for the ordinary person, while there is no great difficulty for the remarkable person. While the remarkable person increases in worthiness by overcoming obstacles, the weak person increases in meanness by running away from them. Problems are comparable to a vicious dog. When it sees you scared or running away, it barks and follows in pursuit. However, when it sees your scorn, your lack of concern, and when you shine your eyes in its direction, it gives way and draws back.
