Prophet Muhammad (PBUH) is an epitome of character and virtue. Besides these humanly characteristics the personality of Prophet Muhammad (PBUH) also contains a vast number of Prophetic attributes such as miracles.
Apart from the miraculous characteristics of the Qur’an which we have looked into so far, it also contains what we can term “mathematical miracles.” There are many examples of this fascinating Qur’anic aspect. One example of this is the number of repetitions of certain words in the Qur’an. Some related words are surprisingly repeated the same number of times.
