Q: What is better in Ramadan – to recite the Qur’an by reading visually or to work on memorization?
A: Your priority is to read the entire Qur’an visually, while also preserving what you have already memorized in order to avoid forgetting it. This is because the entire Qur’an is beneficial for the person to read, as the reader will come across all of the Words of Allah and benefit from the rulings and stories that are contained in its verses. You’ll miss out on all this if you limit yourself only to the chapters that you’d memorize.
By limiting yourself to the specific chapters you memorize, you’ll benefit from them in that your attachment to them will grow. However, this isn’t something you’ll miss out on if you do it at another time because you can recite what you’ve memorized at home, at the mosque, or anywhere else you go.
So, your priority is to make sure you read the entire Qur’an, and then put in extra effort in regards to what you had been memorizing.
