1. Belief in the Oneness of Allah (Tawheed)

The first and most important concept in the Islamic faith is the belief that there is no God except Allah, and He is the sole creator of everything.

Tawheed is Islam's most important and central concept.

Surah Ikhlaas (Chapter 112) in the Holy Quran is dedicated to the oneness of Allah Almighty:

قُلْ هُوَ ٱللَّهُ أَحَدٌ ١

Say, [O Prophet], “He is Allah—One [and Indivisible];

ٱللَّهُ ٱلصَّمَدُ ٢

Allah—the Sustainer [needed by all]

لَمْ يَلِدْ وَلَمْ يُولَدْ ٣

He has never had offspring, nor was He born

وَلَمْ يَكُن لَّهُۥ كُفُوًا أَحَدٌۢ ٤

And there is none comparable to Him
