The existence of all instincts is deemed necessary, and all of them have advantages and uses.
In essence, from this aspect, nothing in the universe has been created inordinately and every integral part of the universe has its own particular function.
So, the existence of all things—evens the apparently worst instincts—is beneficial and necessary.
This all-embracing view on the universe also includes man’s self and instincts. Since there is nothing useless in the universe, it follows that human instincts are also meaningful and purposeful.
The existence of even those instincts which have apparently negative functions is also essential and their absence would render man’s existence imperfect and deficient.
This reasoning has roots in the Qur’anic view of the universe.
God Almighty says: “We created not the heaven and the earth and all that is between them in play.”
In the same vein, since all beings are creatures of the One and Only God, they are in a state of harmony and concordance, and all parts are related to one another.
If in a certain level of existence disorder is noticeable, through a deeper analysis we would realize its intrinsic order.
God Almighty considers it an attribute of the learned and sages that they hold the passing of nights and days and all the phenomena in the universe significance, and say: “Our Lord! Thou createdst not this in vain. Glory be to Thee!”
