Explaining that the Speech of Allah is with voice and letters

The Shaykh : Ibn al-Qayyim says: "and clarification", and this necessitates that the Speech of Allah be with letters and voice, because clarification does not occur unless the speech is heard, and it is not heard except with a voice, and it is not understood except with letters, so the Speech of Allah is also with letters and voice. As for it being with letters, that is because all the speech that Allah spoke is letters; the Qur'an is letters, is it not? And whoever reads it gets ten good deeds for every letter of it. Also, when Allah the Exalted said to Musa the letter lam, the letter nun, the letter ta, the letter ra, the letter nun, the letter ya, what is this? Letters. Good, with a voice or without a voice? With a voice, because Musa heard the Speech of Allah, and likewise the Prophet (peace and blessings be upon him) heard the Speech of Allah on the Night of the Ascension. So the Speech of Allah is with letters and voice, attached to His will, Glorified and Exalted is He, and He has not ceased and does not cease to be a Speaker. Good.
