We all need to understand the Qur'an. If you want to connect with Allah, you have to connect with the Qur’an. You have to understand the Qur'an and apply it in your life. Although, we do not fully understand it, But at some point, We will have a rough idea. People should understand the Qur'an to some level from his mental senses. Those peoples, who's souls have died, Whose bodies have become walking tombs, And they buried within the souls, The Qur'an will not have any effect on them.
