Total number of surahs in the Holy Quran is hundered and fourteen (114), every surah has its own title which is consider as its core of discussion beacause of the importance of a subject for e.g Surah Al-Ahzab the 33rd surah in which Allah Almighty has discussed the event "Battle of Trench" which has a significant importance in the history of Islam, according to arabic lexicon Ahzab mean's group or party of akin minded people. Because in that battle, all those who were keeping a hatred for islam and muslims has joined together and fought a battle against Islam, Muhammad (peace be upon him) and Jamaat momineen.
