During the month of Ramadhan, what is more rewarding to do: tilawat of Qur’an or learning the deen (tajweed, life of Prophet Muhammad saw, going to taleem etc.) ?
Both are necessary. But make a habbit of reciting a portion of the Qur’an every day. Make at least two khatam during the month of Ramadhan. Go and participate in other deeni activities too.
