Qur'an al-karim is word of Allahu Taala
The Quran al-Karim is the Kalam al-Ilahi (Divine Speech, Word of Allahu Taala). Allahu Taala sent the Quran al-Karim to Muhammad (alaihi-salam) through an angel named Jebrail (Gabriel, alaihi-salam). The words in the Quran al-Karim are in the Arabic language, and they descended in ayats (verses), letters and words arranged together by Allahu Taala. The meanings carried by these letters and words convey the Kalam al-Ilahi. These letters and words are called the Quran al-Karim. The meanings that disclose the Kalam al-Ilahi are the Quran al-Karim as well. This Quran al-Karim which is the Kalam al-Ilahi is not a creature. It is eternal and everlasting, like the other Attributes of Allahu Taala. Once every year Jebrail (alaihi-salam) would visit to recite, in the same order as they had been recorded in the Lawh almahfudh (where all matters have been inscribed, in Paradise), the part of the Quran al-Karim that had already been revealed, and our Prophet would repeat it. In the year when he was about to honor the Hereafter, Jebrail (alaihi-salam) visited twice, reciting the entire Quran al-Karim. Our blessed Prophet and most of the Sahaba had memorized the Quran al-Karim wholly. In the year when he honored the Hereafter with his blessed being, Abu Bakr as-Siddiq, the Caliph, brought together those who had memorized the Quran al-Karim and having gathered those parts that had already been written, had a committee write down the entire Quran al-Karim. Thus a written copy called the mus’haf came about. Thirty-three thousand Sahabis reached a consensus that every letter of that copy of the mus’haf was in its right place.
