I can’t agree with you on that point. One of the clearest signs of prophethood is that Allah gives His messengers miracles which no human being can produce. For the final Prophet, the greatest miracle is the Holy Quran, and one of its most astonishing miracles is its language itself.
Anyone who truly understands Arabic and reads the Quran with sincerity can immediately feel that this is not ordinary human speech. Its structure, its rhythm, its imagery, its precision, the way it moves the heart and challenges the mind, nothing in Arabic literature comes close to it. You are already aware that pre-Islamic Arabia was a pinnacle of linguistic mastery. Poets were like celebrities, and the Arabs were unmatched in eloquence. But when the Quran was recited, many of these masters were shaken. Some admitted straight away that no poet, no scholar, no human could ever craft language like this. Many accepted Islam simply by hearing a few verses.
And this miracle is not lost to history. It remains alive today, exactly as it was revealed, preserved in countless written copies and memorized by millions. No other book has ever been protected and transmitted like this.
So if someone truly wants to examine the prophethood of the final Messenger, the most direct way is to study the Quran in its original Arabic. Its miraculous nature is rooted in its language, and no translation can carry that power. That is why scholars throughout history were cautious about translations; they knew that the Quran’s linguistic miracle cannot be reproduced in any other tongue.
