Our Qur'an recitation is still weak. How do we improve our tajwid together as adults?

It is never too late to improve your recitation, and learning as a couple makes the effort easier to sustain. Find a patient teacher, either in person or online, and set regular classes even if short. Check each other's recitation at home without mocking each other's mistakes. Break the goal into small steps: correct the articulation (makhraj) of one letter first before moving on. Record your own recitation and listen back to spot mistakes. Make the learning atmosphere enjoyable, not a place of judgement. Slow, steady progress beats an all-at-once effort that stops. Choose one short surah to perfect together this week. See du'a & prayer.
