What are your tips and guidance for someone who has completed memorizing the Holy Quran?

We congratulate you on your engagement with the Quran, and we ask Allah for sincerity and acceptance for us and for you. We advise you to focus on solidifying your memorization of the Quran, reflecting upon it, understanding its exegesis, performing night prayers with it, and teaching it. Be keen to acquire more knowledge, so study as much as you can of the sciences of Hadith (definition), Aqeedah (creed), Fiqh (jurisprudence), and supporting sciences. Act upon everything you learn so that you may reap the fruits of your efforts.
