Islam encourages a life of balance rather than extremism. A divinely taught blend of worship and relaxation is the key to the door of happiness which western culture has failed to open. The western system advocates a lifestyle of extremes. This mentality, drowned in materialism and capitalism, is then dosed with extremes of pleasure and entertainment in the from of movies, music, sport, comedy, etc. Unfortunately, a substantial proportion of these rely on obscenity and vulgarity which only serve to arouse the base desires and further toss the human soul into an abyss of torment and unhappiness.
The Islamic concept of life is simple and profound: man has been created to worship and obey his Creator, and refreshing the mind with humour should serve as an aid to this objective. Entertainment and humour is not the objective of life. True peace of mind and contentment is in the worship of Allah. Allah, in His infinite wisdom, knows that man requires lighthearted nourishment which tickles the mind and soul, hence provided this example in the lifestyle and conduct of His appointed final prophet, Nabi (ﷺ). It is proven from authentic sources that Nabi (ﷺ) smiled an occasionally indulged in good lighthearted humour.
