As salaamu alaikum wa rehmatullahe wa barakatuhu
Quran is one the most read book in the world Alhamdulilah. It is very important to understand the content which we recite and earn rewards for reciting.
Please read the Summary of each Juz to understand better what exactly we recite and try to increase your knowledge more In sha Allah
May Allah open our hearts to the understanding and help us to implement Quran in our lives. Aamin
