1.peace (root word arabic "salaam")
2.submitting our will to Allah (the only God)
islam is a religion of peace. Its principle is that whatever u do is 4 the will and pleasure of Allah.
It has 5 pillars:kalma, namaz, roza, zakaat, Haj.
Kalma means laa-ila-ha-il-lal-la muhammad-ur-rasool-lul-lah is in arabic
meaning There is no God but Allah and Muhammad (peace be upon him) is is messenger and bondsman/servant.
Namaz is offering prayers 5 times a day.
Roja is fasting in the holy month of ramadhan.
Haj is pilgrimage to mecca to be performed at least once in a lifetime.
Islam includes the belief in the judgement day,heaven,and hell.
That there is going to come one day for sure when this world/earth will be destroyed with all its living beings and all the people who came into existance will be resurrected. There Almighty Allah will calculate everyone's deeds, ones with more of good deeds will go to heaven or paradise for eternity, ones with more of bad deeds to hell fire where only pain lies.
A non muslim, be it athiest or any other religion embracing islam will have all his past bad deeds forgiven and will directly enter paradise.
B proud u came all this far towards truth. Just a few more steps. Remember u take one step closer to Allah, he takes 10 towards u. Islam gives u strength to live with peace, ur soul feels pure. I have so many problems myself i wish to die everyday, Allah, my faith in my heart keeps me going, fighting.
Moreover if u want scientific proof, refer Dr.Zakir Naik's lecture or work on islam and science. U will find various proof that quran really is the word of God/Allah. To embrace islam just read kalma with devotion to its meaning.
Welcome to truth brother/sister.
