Final answer:
The term 'Al-Lawh Al-Mahfuz' describes the Qur'an as a well-preserved Tablet in Islamic belief, signifying its unchangeable and eternally written nature.
Step-by-step explanation:
The Arabic word used to describe the Qur'an as a well preserved Tablet is not explicitly mentioned here, but it is often referred to as Al-Lawh Al-Mahfuz, which translates to 'The Preserved Tablet' in English. This concept has its origins in Islamic belief where the Qur'an is considered the eternally written, perfect and unchangeable text. Muslims believe that the Qur'an they recite and read today is the same as the one preserved in this divine tablet, reflecting God's final and complete guidance for humanity. The preservation of the Qur'an is a testament to its importance and the care taken in transcribing it over the centuries, as reflected in the meticulous development of scripts like Kufic as well as the tradition of oral transmission.
