How to Convert to Islam and Become a Muslim

The word “Muslim” means one who submits to the will of God, regardless of their race, nationality or ethnic background. Becoming a Muslim is a simple and easy process that requires no pre-requisites. One may convert alone in privacy, or he/she may do so in the presence of others.
If anyone has a real desire to be a Muslim and has full conviction and strong belief that Islam is the true religion of God, then, all one needs to do is pronounce the “Shahada”, the testimony of faith, without further delay. The “Shahada” is the first and most important of the five pillars of Islam.
With the pronunciation of this testimony, or “Shahada”, with sincere belief and conviction, one enters the fold of Islam.
Upon entering the fold of Islam purely for the Pleasure of God, all of one’s previous sins are forgiven, and one starts a new life of piety and righteousness. The Prophet said to a person who had placed the condition upon the Prophet in accepting Islam that God would forgive his sins:
“Do you not know that accepting Islam destroys all sins which come before it?” (Saheeh Muslim)
When one accepts Islam, they in essence repent from the ways and beliefs of their previous life. One need not be overburdened by sins committed before their acceptance. The person’s record is clean, and it is as if he was just born from his mother’s womb. One should try as much as possible to keep his records clean and strive to do as many good deeds as possible.
The Holy Quran and Hadeeth (prophetic sayings) both stress the importance of following Islam. God states:
“...The only religion in the sight of God is Islam...” (Quran 3:19)

In another verse of the Holy Quran, God states:

“If anyone desires a religion other than Islam, never will it be accepted of him; and in the Hereafter, he will be in the ranks of those who have lost (their selves in the Hellfire).” (Quran 3:85)

In another saying, Muhammad, the Prophet of God, said:

“Whoever testifies that there in none worthy of being worshipped but God, Who has no partner, and that Muhammad is His slave and Prophet, and that Jesus is the Slave of God, His Prophet, and His word[1] which He bestowed in Mary and a spirit created from Him; and that Paradise (Heaven) is true, and that the Hellfire is true, God will eventually admit him into Paradise, according to his deeds.” (Saheeh Al-Bukhari)

The Prophet of God, may the blessing and mercy of God be upon him, also reported:

“Indeed God has forbidden to reside eternally in Hell the person who says: “I testify that none has the right to worship except Allah (God),’ seeking thereby the Face of God.” (Saheeh Al-Bukhari)

The Declaration of the Testimony (Shahada)
To convert to Islam and become a Muslim a person needs to wash his allbody first and pronounce the below testimony with conviction and understanding its meaning:

I testify “La ilah illa Allah, Muhammad rasoolu Allah.”

The translation of which is:

“I testify that there is no true god (deity) but God (Allah), and that Muhammad is a Messenger (Prophet) of God.”
