Why is religion important in peoples lives?

Because they are indoctrinated as children

they know no other way than to believe in their religion, this is what they have been trained to believe is right and that everything else is wrong

When a young child is surrounded with religion their whole lives, they never even consider that what they are taught is not true, they become conditioned.

...

Without knowledge of the purpose of creation, human beings wander aimlessly through life, like ships at sea without rudders. Their goals are either wrong due to incorrect religious teachings, or materialistic and thus confined to this world. It is, therefore, essential for their own well-being that they know why God created them. Fundamentally, Allah created in order to manifest His attributes. Consequently,

Creation is the consequence of His being the Creator

Paradise manifests His Mercy and Grace

Hell, His justice

Humankind's errors, His forgiveness

Living and non-living beings, His Generosity, etc.

The significance of knowing that creation is a means by which Allah manifests His attributes is that human beings can then correctly recognize God and accept His decree and their destiny.

For many folks, particularly more so the Muslims, everything they do is imbued and defined by their faith, how they eat, bathe, dress, time that they pray, diet, and yes even fart if you can believe that, is dictated by their faith.

They don't consider it legalese but an all encompassing expression of their faith that touches every aspect of their lives.

Compartmentalized westerners have a hard time understanding this since they can be weekend Christians and weekly devils in practice with little trouble since much of life in this side of the world is fragmented into so many roles.

It gives a sense of connectedness to the rest of the Universe.

Gives live meaning.

Provides solace.

Gives ethical guidlines (if only people would follow them).

Provides a sense of morality (right and wrong) to people for the purpose of creating an ethical society to live in.

religion gives us mere mortals something to belive in and a sense of purpose,if we didnt have heaven or the afterlife to look forward to what would be the purpose of existance!? you live you die..not much fun in that!

Because then most people would not find a reason or purpose for living.

Because humans have an inherrent spiritual side that they need to satisfy, & everyone fills that need with something, whether it actually satisfies their need, or not.

Because they are very scared of dying and need a comforting alternative.

cuz it is the law
