50. Gist of our faith is:
La Ilaha Illallah Muhammadur Rasulullah. (There is no god but Allah, Muhammad is the Messenger of Allah.) Our belief, which we hold in this life here on earth and to which we will continue to adhere firmly till the time that we pass on to the next world, is that our spiritual leader and master, Muhammad, peace and blessings of Allah be on him, is the Seal of the Prophets and the Best of the Messengers. At his hands religion has been perfected and blessing of Allah has been consummated which lead man to the right path and further on to God Himself. We hold this positive belief with absolute certainty that the Holy Quran is the seal of all Divine books and not an iota can be added to or subtracted from its prescribed teachings, inhibitions, commands and injunctions. There will be no revelation or word from God which may amend or abrogate or change or alter any of the injunctions of the Holy Quran. If anyone subscribes to such views, in our opinion, he ceases to belong to the body of believers and becomes an infidel thereby.

51. We do believe that there is none worthy of worship except God Almighty and Sayyedena Hazrat Muhammad, the Chosen One, may peace and blessings of Allah be upon him, is His Messenger and the Khatamul Anbiya. We believe that angels are a reality, that Resurrection is a reality and the Day of Judgement is a reality; that Heaven is reality and so is Hell. We do believe that whatever the Glorious and Majestic God has stated in the Holy Quran and whatever our Prophet, may peace and blessings of Allah be upon him, has stated is all, according to the aforementioned statement, the truth. We do believe that the person who subtracts an iota from the Islamic law or adds to it as much, or lays the foundation in any manner for rejection of Islamic injunctions, or attempts to declare unlawful what has been made lawful in Islam, is an infidel and a renegade to Islam. We admonish our Jamaat that they must adhere tenaciously to the fundamental article of Islamic faith.
"There is no God but Allah, Muhammad is His Messenger" as long as they live and that they should die holding fast to the same belief. Also they must have firm faith in all the Messengers of Allah and revealed Books which have been authenticated by the Holy Quran. They should abide strictly by the Quranic injunctions. They should strictly observe Prayers and Fast, pay Zakat and perform the Haj (pilgrimage). They should observe Islam by fully complying with all the injunctions, obligations and prohibitions pronounced by God and His Messenger. In short, all such matters, be they beliefs or deeds, on which there was consensus of opinion among our righteous predecessors and as are understood to be Islam by the general consensus of opinion of those who follow the traditions of the Holy Prophet of Islam, may peace and blessings of Allah be upon him, should be complied with as being obligatory. We call to witness the Heaven and the Earth, that exactly is our Faith."

52. O ye who inhabit the earth! And O ye human spirits who dwell in the East or in the West! I invite you most earnestly to accept the fact that the only true faith today in the world is Islam and that the True God is that God who has been mentioned in the Holy Quran, and that Prophet who possesses eternal spiritual life the one who sits on the throne of glory and purity is the Holy Prophet Muhammad, the chosen one, may peace and blessings of Allah be upon him.
