First i would thank the 
MEANING OF SPIRITUALITY
When you talk about spirituality , there must be faith.
No spirituality without Faith
Faith is to believe in something.
This involves attaining a spiritual level, connecting with spirits from other world. Being able to build yourself with things of the spirit, walking in the spirit.

Outside our physical world i believe that there is another world that exists and most people know or may not know about.
There is another realm of the spirits that goes on in another world, where things beyond the human comprehension takes place. Things that above human powers , supernatural things.
There is a supernatural being that controls this spiritual realm and the physical, maybe not all of it but most of it, this supernatural being is believed to be known as God by the christians. Whom created the heavens and the earth and every other thing in the universe.
I believe in God , many people also do no matter what name we call him or them in our different tribes or believes.
Most people say there is a God while others say there is no God.
Everyone sees things different depending on there experience, believe , encounter etc.
Now a Muslim calls God Allah and believes in prophet Mohammed as there saviour
Christians on the other hand believes in God and Jesus Christ as there Lord and personal saviour.
Other believes in Buddha and many other Gods.
The christians celebrate Christmas and Easter while Muslims celebrate Salah and Eid Mubarak etc.
In the Quran Muslims are being told that when they die in battle or while taking another man's life , they would go to heaven and get rewarded with virgins.
Now someone with such mentality would always want to cause confusion , mayhem or possibly war.

The christians not believing in alot of things being taught in the Quran sees Muslims as people twarting the truth and thereby the hate started building up amongst them.
Making them kill each other at some point ( The War sets in ).
I think spirituality should be looked at above what we see in or being taught in church or mosque.
Spirituality comes from within and can be self developed, you don't need a church or mosque or bible or Quran to be spiritual.
RATHER
You need the truth to be spiritual
When you know the right thing and you do it
When you decide to be a peace maker
When you become a pacesetter
Work on being an ambassador of truth and love
Love one another , care for one another whether they share the same faith with you or not.
Don't hate

I believe that's what SPIRITUALITY should be all about.
