Which repetitions are you talking about?
I know vaguely of certain phrases and ideas that are repetitive throughout the book, such as the constant assertion and reassertion of
Muhammad being the messenger of Allah, and Allah knowing everything. These repetitions reinforce the belief in God and Muhammad the messenger, which is fundamental to keep his followers.
hello Aqua ., just to let you and other readers know ............ Quran mentions the word "Muhammad" only four times and those verses are
3.144: And Muhammad is no more than an apostle; the apostles have already passed away before him; if then he dies or is killed will you turn back upon your heels? And whoever turns back upon his heels, he will by no means do harm to Allah in the least and Allah will reward the grateful.
33.40: Muhammad is not the father of any of your men, but he is the Apostle of Allah and the Last of the prophets; and Allah is cognizant of all things.
47. 2: And (as for) those who believe and do good, and believe in what has been revealed to Muhammad, and it is the very truth from their Lord, He will remove their evil from them and improve their condition.
48. 29: Muhammad is the Apostle of Allah, and those with him are firm of heart against the unbelievers, compassionate among themselves; you will see them bowing down, prostrating themselves, seeking grace from Allah and pleasure; their marks are in their faces because of the effect of prostration; that is their description in the Taurat and their description in the Injeel; like as seed-produce that puts forth its sprout, then strengthens it, so it becomes stout and stands firmly on its stem, delighting the sowers that He may enrage the unbelievers on account of them; Allah has promised those among them who believe and do good, forgiveness and a great reward.
so that word "Muhammad"
is not used repeatedly in Quran
with best wishes
