Shahada in Islam

The most fundamental and the most important teaching of Prophet Muhammad (blessings of Allah and peace be upon him) is faith in the unity of God. This is expressed in the primary Kalimah of Islam as "There is no deity but Allah" (La ilaha illallah). This beautiful phrase is the bedrock of Islam, its foundation and its essence. It is the expression of this belief which differentiates a true Muslim from a kafir (unbeliever), mushrik (one who associates others with God in His Divinity) or dahriyah (an atheist).

The acceptance or denial of this phrase produces a world of difference between man and man. The believers in it become one single community and those who do not believe in it form an opposing group. For the believers there is unhampered progress and success in this world and in the hereafter, while failure and ignominy are the ultimate lot of those who refuse to believe in it.

But the difference between the believers and the unbelievers does not result from the mere chanting of a few words. Obviously, the mere utterance of a phrase or two is not in itself important. The real difference lies in the conscious acceptance of this doctrine and complete adherence to it in practical life. Mere repetition of the word 'food' cannot dull hunger; mere chanting of a medical prescription cannot heal the disease.

In the same way, if the Kalimah is repeated without any understanding, it cannot work the revolution which it is meant to bring about. This can occur only if a person grasps the full meaning of the doctrine and accepts and follows it in letter and spirit. We avoid fire because we know that it burns; we keep away from poison because we know that it can kill. Similarly, if the real meanings of Tawhid are fully grasped, we avoid, in belief as well as in action, every form of disbelief, atheism and polytheism. This is the natural consequence of belief in the Unity of God.
