Watch: Why Muslims believe God is One - Tawheed explained

Tawheed (توحيد) is the most fundamental concept in Islam. It means the absolute oneness of God. Understanding Tawheed is understanding the heart of Islam.

قُلْ هُوَ اللَّهُ أَحَدٌ ۝ اللَّهُ الصَّمَدُ ۝ لَمْ يَلِدْ وَلَمْ يُولَدْ ۝ وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ

Say, "He is Allah, [who is] One, Allah, the Eternal Refuge. He neither begets nor is born, Nor is there to Him any equivalent."

This short chapter (Surah Al-Ikhlas) is so important that Prophet Muhammad ﷺ said it equals one-third of the Quran! It perfectly summarizes who Allah is:

• Allah is ONE - Not two, not three, just one • Allah is Eternal - He was always there, will always be there • Allah has no family - No sons, daughters, or parents • Nothing is like Allah - He is unique, beyond our imagination

Scholars explain Tawheed in three parts:

1. Tawheed ar-Rububiyyah (Lordship) Believing that Allah alone is the Creator, Sustainer, and Controller of everything.

2. Tawheed al-Uluhiyyah (Worship) Directing all worship to Allah alone - no prayers to anyone else.

3. Tawheed al-Asma wa Sifat (Names & Attributes) Believing in Allah's beautiful names and attributes as He described Himself.

Don't worry if this seems complex! The simple version is: There is ONE God, He created everything, and we worship only Him. That's Tawheed!

Tawheed matters because it gives you:

• Freedom - You're not slave to money, people, or idols • Peace - Only One God to please, not many • Purpose - You know why you exist • Hope - You have a direct connection to your Creator
