 There are linguistic subtleties in the Quran that the Prophet sallallahu alayhi wa sallam could not have known. Allah SWT says kafa ya'in sard vikru rahmatirabbika abdahu zakariya. The name zakariya in Hebrew means the mention of the Lord. This is what his name zakariya in Hebrew means, the mention of the Lord. So this verse is a play on words, vikru rahmatirabbika abdahu zakariya, the mention of the mercy of your Lord to His servant, the mention of the Lord. There's this beautiful subtle symmetry in this one ayah. The author of this ayah knew Hebrew, there's no doubt about it. If a Jew living in the hijaz heard this verse, his ears would perk up. He would notice the subtlety. Another example, Allah SWT says wamratu qaimatan fata'ikat fa basharna habi ishaq. And the wife of Ibrahim sallallahu alayhi wa sallam, she laughed and then we gave her glad tidings of Isaac. Isaac means laughter. And then it says wamin warayhi ishaq ya'qub, wamin warayhi ishaqa ya'qub. And then following Isaac, Jacob. The name Isaac means laughter in Hebrew. The name Jacob means to follow or to come after. This is a type of word play that adds to the eloquence and brilliance of the Quran. Whoever composed this verse knew Hebrew. Of course we know this is a revelation from Allah SWT. I'll give you another example. There's hundreds and hundreds, if not thousands of these types of examples. Allah SWT says yachya alayhi sallam, wa hanana milladuna wa zakatan wa kana taqiyyah. Now yachya is John, John the Baptist, he's be upon him. Most probably. The Quran calls him yachya meaning he lives because he was martyred and the martyrs are alive. They're alive with their Lord, receiving sustenance from their Lord. But the Hebrew name of John is yohanan which is related to hananan, wa hanana milladuna wa zakatan wa kana taqiyyah. This is the only occurrence of this word in the entire Quran and it's describing yachya alayhi sallam because it actually relates to his historical name. These are subtleties that go over the head of 99% of the Quran's readers. The author of the Quran is playing with these languages in a masterful way.
