It is necessary for every Muslim to get acquainted with his religious obligations and know about his duty. Therefore, a person will get sawab by listening to a speech that enables him to become familiar with his religious duties and obligations. The Holy Prophet of Islam (S) says about acquiring religious knowledge and becoming familiar with divine prohibitions and commandments, "Acquiring knowledge for God's sake is a good deed (which earns the seeker divine reward), and searching for knowledge is an act of worship and discussing a scientific issue amounts to glorifying the Lord and acting upon is tantamount to Jihad."
"Since halal and haram can be known through knowledge, knowledge is the light that brightens the path to Paradise, it is the solacing friend in time of fear, a companion in time of loneliness, it is an intimate comrade whom he talks to when he is forlorn; it is guide in time of happiness and grief, a weapon against the enemy and an ornament and beautification in the eye of friends."
As well, Imam Jawad, peace be upon him, said: "Whoever listens to a lecturer, he has worshipped him. So, if he speaks of God, he has worshipped God and if he speaks of Iblis (devil), he has worshipped Iblis."
It should be noted that learning Islamic law and acquiring religious knowledge is not restricted to any given day or occasion, though Friday has been introduced in the narrations as a day in which Muslims engage in learning and acquiring religious knowledge. As said by Imam Sadiq (A.S.), the sixth Shia Imam, "It is not appropriate of a Muslim not to spend his Friday in a regular basis for a religious activity to acquire religious knowledge."
