It is written in Burhan-i qati' that Plato lived during the time of 'Isa 'alaihissalam'. And in European books, it is written that he died three hundred and forty-seven (347) years before the honourable birth of Isa (alaihissalam). Since the teachings of this Greek philosopher are famous, his time of death is dependable. But, because Hadrat Isa 'alaihissalam' was born secretly, taken up to heaven after a short life in the world and known only by his twelve apostles, and because the Isawis (his followers) were few and they lived in seclusion for centuries, Christmas Eve, that is, his birthday, could not be determined correctly. Along with the fact that the birthday is estimated to be on December twenty-fifth or January sixth or some other day, it is written in books in various languages, and for example, Hasib Bey's book Kozmografya [edited in 1333 A.H. (1915)], and also in Taqwim-i-Abuzziya, that today's years of the Christian era are lacking five years. Then the anno domini, unlike Muslims' year, hijri, is not correct and certain, and its day and year are doubtful and wrong. As Hadrat Imam-i Rabbani 'quddisa sirruh' and Burhan-i qati' note, it lacks more than three hundred years, and the elapse of time between Isa 'alaihissalam' and Muhammad 'alaihissalam' is no less than a thousand years. It is written in the third chapter of the second volume of Mawahib-i ladunniyya, "As Ibni Asakir quotes from Sha'bi, there are nine hundred and sixty-three (963) years between Hadrat Isa and Hadrat Muhammad."

Constantine the Great, formerly a pagan, accepted Christianity, and after enlarging and improving the city, he gave it the name Constantinople (now known as Istanbul). In the year 325 A.D. he convened three hundred and nineteen priests in Nicea, ordered all the Bibles to be united and a new Bible to be written, having many articles of paganism from his former religion inserted into it. Accepting Christmas Day as the beginning of the year, he established a new Christian religion. It was declared in the Injil (the real Bible) of Hadrat 'Isa and in the Bible written by Barnabas that Allah is one. Yet, because they did not have the original Injil, the idea of the Trinity put forward by Plato, whom they esteemed as a philosopher, was included in these four defiled books. Constantine had this idea of Trinity put into the new Bible together with many fabled writings. A priest named Arius said that this new Bible was wrong, that Allah is one, that Hadrat 'Isa was not His son but His born slave, yet they wouldn't listen to him. They excommunicated him. Arius fled to Egypt and spread the tawhid (unity of Allah) there, but he was killed.

The enemies of Islam, in order to deceive Muslims, try to hide the fact that it is kufr to adopt the customs of the disbelievers and to celebrate their festivals. They call these customs 'Islamic customs' and these days 'sacred days'. They represent the Noel (Christmas), which was introduced into Christianity by Constantine the Great, and Nawruz, which was invented by Jamshid as a national celebration; and they want Muslims to accept the same things. Young and innocent Muslims should not fall into their traps.
