Does reading without memorization diminish the reward or render it unacceptable, given continuous reading and the inability to memorize by heart?

Memorizing the Noble Qur'an is a tremendous project that requires high resolve and strong determination. It is made easy for whomever Allah makes it easy for, as He the Almighty said: "And We have certainly made the Qur’an easy for remembrance, so is there any who will remember?" (Qur’an 54:17). To achieve this, one must strive diligently and seek Allah's help through piety, while reviewing current memorization methods by utilizing the guidance mentioned in Fatwas numbered: 31956, 33636, 34391, 39644, and 46616. Every recitation of the Qur'an contains goodness and blessing, and its reward varies; the one who is skilled in the Qur'an will be with the noble and righteous scribes (angels), and the one who recites the Qur'an falteringly and it is difficult for him will have two rewards. As for "recitation without memorization from thought," its meaning is unclear.
