The Miracles of Prophet Muhammad were seen, heard, and witnessed. The news of these miracles that prove his Prophethood, were told through a "chain of narrators". In Islam we have something called chain of narrators. That is a chain of scholars that narrate the sayings of the Prophet that they heard from him. These narrators have to be qualified to narrate. And the unique matter about these narrators, is that they are more than from different countries and places, they all report in their books, the same saying or similar meaning of it, which makes it impossible for all of these narrators that come from different places to agree on a lie.
Just to remind you, Prophet Muhammad was not a scientist to know all these things.
Islam is Easy, simple and straightforward.
No legends, JUST FACTS. The truth, and nothing but the truth.
So this affirms the validity of what the Prophet tells about. Because it's intellectually impossible for all these people to unanimously agree on a lie, since they all were from different regions, and had delivered the sayings of the Prophet when they went back home.
And many other proofs in al-Quran that removes the doubt of the person about the origin of this world, and about the upper world, and other planets... and fills his heart with pure beliefs that comply with the sound mind. They all are in the Quran and will always be the strong reason for the MILLIONS of people that are becoming Muslims and steadfast to that religion.
It's because Islam is the only true religion that the sound mind accepts. And other religion other then Islam are fabricated and that the bible is perverted, the current bible is authored by man, and my proof is that there are thousands of thousands of different versions of it with different messages and for different sects; they all claim that it's the word of God.
How could we know which is the true message of God?
We can't, unless that message is authenticated, and in the bible there's no authentication.
We urge those who didn't embrace Islam, to accept Islam, and leave the contradictive and ill beliefs; that Jesus became God, or son of God... We also urge them to leave the belief that, Jesus died for the sins of the creations (!)... And to leave the belief that Jesus, the human, is worthy of being worshipped. Or that God was killed on the cross or any false belief like that!
Islam is about faith:
・Islam is to believe in the oneness of Allah
・All Prophets were Muslims. They all believed in the oneness of Allah
・Differences of the laws of the Prophets
・Quran is the holy book that Allah revealed onto Prophet Muhammad
・Proving that the Quran is a revelation from Allah
・Miracles of Prophet Muhammad confirm his prophethood
・Chain of narrators that convey what they heard from the Prophet from one generation to the other continuously
After this brief summary, we urge any non-Muslim, to look with open mind to these brief tips, that were offered by Islamic proofs AND intellectual proofs that we both must comply with. Because Allah made a common thing among humans, it's the intellect.
A person becomes a Muslim by leaving all that contradicts the meaning of the following Testification of Faith, believing in the heart and declaring with the tongue:
TO BE A MUSLIM NOW, JUST SAY and BELIEVE that "No one is God but Allah and Muhammad is the Messenger of Allah"
Believing in all this implies--Allah, the Creator, has perfect attributes, only Allah must be worshipped, Prophet Muhammad, the last prophet, was truthful in all that he conveyed from Allah, all the prophets before him (the first of whom was Adam) conveyed the same message of belief to their people and are to be loved and respected, yet in no way do prophets (or any creation) have Allah's attributes.
A person can become Muslim, as aforementioned in the solitude of a forest or in a crowded subway; he does not need to go to a mosque or have Muslims witness his profession.
Allah knows the hearts of His creation. However, when he becomes Muslim he may declare his belief to some fellow Muslims so he will be known as a Muslim among the people.
We urge those who don't believe in Allah and his Prophets, to accept Islam, and leave the contradictive and ill beliefs; such as claiming that Jesus became God, or son of God, or that Jesus died for the sins of the creations (!) which he didn't commit, or the belief that Jesus, the human whom Allah created him, is worthy of being worshipped, Or that "God was killed" on the cross or any false belief like that!
Know that the belief of the Muslims is that Allah: has no partner, is the creator of everything, does not need any of his creations, and absolutely nothing resembles Allah. Whatever you imagine in your mind Allah is different from it. Prophets are chosen humans that Allah sent to people to teach them about the religion.
Islam is the only true religion and is the only right way of life.
Person becomes a Muslim by leaving all that contradicts the meaning of the following Testification of Faith, believing in the heart and declaring with the tongue:
"No one is God but Allah and Muhammad is the Messenger of Allah"
To anyone who becomes Muslim while reading this, we advise you to seek knowledge as to the practice of Islam from a trustworthy Muslim teacher. As people go to college to be taught by those learned on different subjects, one should go to a learned Muslim to learn about the practice of Islam. There will always be more to learn and more ways to improve for a devoted Muslim, so arrogance is not a part of a good Muslim's life.
Allah is the one who guides to the truth, and Allah knows best.
