The fact that always be considered is the contemplation of internal feelings of every practiced Muslim to please Almighty Allah. It occurs via observing and following His commands and orders through prescribed manner of the Messenger Muhammad Peace Be upon Him, but sometimes it becomes so complex and multipart to identify the right step of actions, streamline with shariah standards even difficult to recognize the difference between preferred and Non-preferred, lawful and prohibited. So among these situations, second congregational prayed in one masjid, an issue faced by common people. The classical literature is the witness of unanimous ruling in two situations of second congregational prayer; i.e. congregation (Jama’at) in the Masjid and congregation in public places. The third situation requires little deep understanding to know the actual ruling of shariah, which is congregation (Jama’at) in the same Masjid but appointed Imam performs original Jama’at. Different scholars have presented different opinions. This paper emphasis on the third situation where the detailed discussion has been made in the light of the mentioned book in the title to draw the neat and clear line of action for the practiced Muslim along with the provision of different narrations and Shariah rulings in order to interpret the reality and to avoid all sort of confusions.
