بسم الله الرحمّن الرحيم
يَا أَيُّهَا النَّاسُ إِنَّا خَلَقْنَاكُم مِّن ذَكَرٍ وَأُنثَىٰ وَجَعَلْنَاكُمْ شُعُوبًا وَقَبَائِلَ لِتَعَارَفُوا
 ۚ
إِنَّ أَكْرَمَكُمْ عِندَ اللَّهِ أَتْقَاكُمْ ۚ
إِنَّ اللَّهَ عَلِيمٌ خَبِيرٌ

صدق الله العظيم

O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honored of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).

                 How to become a Muslim                     

If anyone has a real desire to be a Muslim and has full conviction and strong belief that Islam is the true religion ordained by Allah (God) for all beings, then, one should pronounce the "Shahada شهادة",

'La ilaha  il Allah, Muhammad-ur-Rasool-Allah'

La ilaha il Allah, Muhammad-ur-Rasool-Allah

(None has the right to be worshiped but Allah, and Muhammad is the Messenger of Allah)

the testimony of faith,without further delay. The Holy Qur'an is explicit on this regard as Allah states:

"The Religion in the sight of Allah is Islam." (Qur'an)

In another verse of the Holy Qur'an, Allah states:

"If anyone desires a religion other than Islam (Submission to Allah), Never will it be accepted of him; and in the Hereafter he will be in the ranks of those who have lost."(Qur'an)

If a person does not pronounce the Shahada and enter Islam, we cannot say that he is a Muslim, even if he admired Islam and recognized that it the best religion, a great religion, and so on. Abu Talib, the uncle of the Prophet (peace and blessings of Allah be upon him) died a Kafir (non-Muslim), and Allah forbade His Prophet to pray for forgiveness for him, even though he used to defend the Prophet (peace and blessings of Allah be upon him) and said in his poems: "I do know that the religion of Muhammad is better than all other religions of mankind; were it not for fear of  blame or slander, you would find me accepting it completely."
