Most adults who come to us have tried once before. They bought a Qaida, worked through a few pages, and stopped — not because the book was wrong, but because nobody was listening to them read aloud. Reading the Quran is a spoken skill before it is a written one, and a spoken skill needs a listener who can correct you in the moment.
So begin with the letters, out loud, with someone who can hear you. The Arabic alphabet has twenty-eight letters, and roughly a third of them make sounds English does not use at all. The throat letters in particular — ha, kha, ain, ghain, qaf — are the ones adults tend to substitute with the nearest English sound without noticing. A teacher catches that in the first week. A book cannot.
Once the letters are secure, the short vowels come next, then joining letters into two- and three-letter words. This is the stage where progress feels slowest and matters most. Resist skipping ahead to full verses because they are more rewarding to read; a shaky foundation shows up later as a habit that takes three times as long to unlearn as it took to form.
Expect the Noorani Qaida, or something very like it, to carry you through all of that. It is a graded reader, not a textbook — every page exists to drill one new thing against everything you already know. Working through it properly is the single biggest predictor of whether an adult beginner is still reading a year later.
Two practical notes. Fifteen focused minutes a day beats an hour on Saturday, because the muscles involved in articulation respond to frequency rather than duration. And read aloud even when you are alone, because silent reading lets errors pass unnoticed.
If you are not sure which level to start at, ask for an assessment rather than guessing. A short read-aloud tells a teacher more than any questionnaire, and it saves you from spending weeks in the wrong book.
