Allah (Exalted be He) has made easy the means that help memorizing His Ever-Glorious Book, so you should follow such means. The best means is to learn the Qur'an at the hands of one of the trustworthy scholars, who can instruct you, correct your mistakes and point out the meaning to you. We advise you to recite the Qur'an as much as possible, for this entails a great reward and guides you to all goodness. Allah (Glorified be He) says:
Verily, this Qur’ân guides to that which is most just and right
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
