Forgetting the Qur'an

Q 2: When I was young, I memorized five Juz’s (a Juz’ equals a 30th of the Qur’an) twice and forgot them later. I am trying very hard to memorize them again at an old age, but in spite of reading the Qur’an frequently from the Mus-haf (copy of the Qur’an), I feel incapable. I fear Allah’s saying in Surah Ta-Ha, Ayah (126): (Allâh) will say: "Like this: Our Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) came unto you, but you disregarded them (i.e. you left them, did not think deeply in them, and you turned away from them), and so this Day, you will be neglected (in the Hell-fire, away from Allâh’s Mercy)." Does the Ayah mentioned here refer to the Ayahs (verses) of the Qur’an or the Ayahs (signs) of Allah in the universe?

A: Disregard here means to neglect acting upon them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
