Islam is pure Monotheistic religion, which teaches:
Worship the creator; not creations like humans, animals, inanimate objects, nature, fire, trees, water, sun, moon, stars, holy books, country or flag.
As per Islam, Allah (GOD) created us and gave us shape and structure but we humans cannot create God and give shape and structure to GOD in the form of statutes, idols or paintings; who is unseen.
Allah (GOD) is only ONE (not 3,5,10 or 330 million etc.)
Allah (GOD) is Unseen (no one knows the shape and color and size and structure)
Allah (GOD) is ETERNAL (never born and never dies)
Allah (GOD) has no parents, nor wife and no children like human beings and animals
Allah (GOD) is not a human, nor animal, nor inanimate object, nor nature, fire, trees, air, water, land etc.
Islam is the oldest religion, Muhammad (Peace be upon Him) is the last messenger and Qur’an a religious book revealed by ALLAH (GOD) for the guidance of human kind.
Islam has 5 pillars: Tauheed (Belief in ONE creator), Salah (Namaz), Saum (Roza), Zakat (Charity) and Hajj (Pilgrimage)
