We believe that Allah chose Islam as the true religion. In the Qur'an, He says: {And I have chosen Islam as your religion.} [Surat al-Mā’idah: 3] He also says: {The true religion with Allah is Islam.} [Surat Āl ‘Imrān: 19] And it is the religion of all prophets and messengers (peace be upon them). Nūh (peace be upon him) is quoted in the Qur'an as saying: {And I have been commanded to be among those who submit to Allah [as Muslims].} [Surat Yūnus: 72] About Ibrāhīm (peace be upon him), Allah Almighty says: {When his Lord said to him, 'Submit,' he said: "I have submitted to the Lord of the worlds."} [Surat al-Baqarah: 131]
We believe that our Lord perfected this religion for us; so, it does not have any aspect of deficiency. Allah Almighty says: {Today I have perfected your religion for you, completed My favor upon you, and have chosen Islam as your religion.} [Surat al-Mā’idah: 3] It is the best, most complete, and most perfect among all religions; it is the religion of true devotion to Allah, the religion of Ibrāhīm (peace be upon him). Allah, Exalted be He, says: {Who is better in religion than one who submits himself entirely to Allah, does good, and follows the religion of Abraham, exclusively devoted to Allah? For Allah did take Abraham as a close friend.} [Surat an-Nisā’: 125] He also says: {Who would forsake the religion of Abraham except a fool! We have chosen him in this world, and in the Hereafter he will be among the righteous.} [Surat al-Baqarah: 130] About Prophet Ibrāhīm (peace be upon him), Allah, the Exalted, says: {Abraham was neither a Jew nor a Christian, but he was a monotheist Muslim, and he was not one of the polytheists.} [Surat Āl ‘Imrān: 67]
It is the natural disposition with which Allah created mankind. In the Qur’an, He says: {Adhere sincerely to the true religion in all uprightness. This is the natural disposition with which Allah has created mankind. There is no change in Allah’s creation. This is the straight religion, but most people do not know.} [Surat ar-Rūm: 30]
And the Prophet (may Allah's peace and blessings be upon him) said: "Every child is born upon the natural disposition, and then his parents convert him to Judaism, Christianity, or Magianism. As an animal delivers a perfect baby animal, do you find it mutilated?" Abu Hurayrah (may Allah be pleased with him) added: {This is the natural disposition with which Allah has created mankind. There is no change in Allah’s creation. This is the straight religion.} [Surat ar-Rūm: 30] [Narrated by Al-Bukhāri (1385), Muslim (2658), Abu Dāwūd (4714), and At-Tirmidhi (2138)] And it is the covenant Allah Almighty took from Adam and his children. Our Lord says: {And [remember] when your Lord brought forth from the loins of the children of Adam their offspring and made them testify about themselves [asking]: "Am I not your Lord?" They said: "Yes indeed; We testify." [We did so] lest you should say on the Day of Resurrection: “We were unaware of this.”} [Surat al-A‘rāf: 172]
We believe that Allah does not accept any other religion. He, Exalted be He, says: {Anyone who seeks a religion other than Islam, never will it be accepted from him; and in the Hereafter he will be among the losers.} [Surat Āl ‘Imrān: 85]
