And We certainly know that they say, "It is only a human being who teaches him [i.e., the Prophet (ﷺ)]." The tongue of the one they refer to is foreign, and this [recitation, i.e., Qur’ān] is [in] a clear Arabic language.
And if We had made it a foreign [i.e., non-Arabic] Qur’ān, they would have said, "Why are its verses not explained in detail [in our language]? Is it a foreign [recitation] and an Arab [messenger]?" Say, "It is, for those who believe, a guidance and cure." And those who do not believe - in their ears is deafness, and it is upon them blindness. Those are being called from a distant place.
Why do the numbers differ from one website to another?
Some count the root (every word built on it), others a single word, others the exact form as written in the Mushaf: all three numbers are given here.
Prefixes and suffixes (و، ب، ال…) are taken into account; a search on the raw text may miss some, or count words from another root that are spelled the same way.
The counts follow the Hafs reading and the grammatical analysis of each of the 77,429 words of the Quran.
Results are ranked automatically: only texts of the Quran and translations of their meaning are shown, with no machine-written text. For a legal opinion, consult a scholar.
