Praise be to Allah, Who sends the prophet (PBUH) to explain His Holy book to mankind, and He is the master of all things, Who revealed the Quran to the prophet. However, the Quran is not a creation it was revealed by Allah.
Allah told us, as He says in the Holy Quran:
“And who is truer in statement than Allaah?[al-Nisaa’ 4:87]
“and whose words can be truer than those of Allaah?
These two verses prove that Allah speaks and also that He only speaks what is true. Allaah speaks in a real sense.
Hence the belief of Ahl al-Sunnah wa’l-Jamaa’ah is that Allaah speaks in a real sense, with letters and sound, however, this does not resemble the voices of created beings. As proof:
“There is nothing like Him, and He is the All‑Hearer, the All‑Seer”[al-Shoora 42:11]
In the evidence that the Qur’an is not created is the saying:
“Surely, His is the creation and commandment”[al-A’raaf 7:54]
In this verse, Allaah describes creation as one thing and commandment as another. It implies that the second thing mentioned is different, and the Qur’an is part of the commandment because of this verse:
“And thus We have sent to you (O Muhammad) Rooh (a revelation, and a mercy) of Our Command. You knew not what is the Book, nor what is Faith? But We have made it (this Qur’an) a light wherewith We guide whosoever of Our slaves We will”
All praise to Allah and he knows best.
