Pondering and thinking over the contents of the verses of the Surah which usually act as a verbal chain of events that tell us if the Surah was revealed in Makkah or Madinah. Seeing as how the cities of Makkah and Madinah were two completely different environments, we understand that each was governed by its own ways of thought, and thus the religion of Islam was put face to face with issues and difficulties which were specific to that particular area.
Thus, after we are acquainted with the way of thinking and the particular issues of an area (Makkah or Madinah), and we have studied the contents and verses of a Surah, then we are then able to discern where the Surah or the verses of the Surah were revealed. For instance, the environment of Makkah was one polluted with polytheism and idol worship. The Jews and Christians had not permeated into this city and thus, those who had true faith (Iman) were very small in number.
The issue of Jihad and fighting were not brought up in this environment and the Prophet (blessings of Allah be upon him and his progeny) had frequent dealings and relations with the idol worshippers.
Therefore, the point of difference of the Prophet (blessings of Allah be upon him and his progeny) with the polytheists (of Makkah) was concerning Tawhid (the Oneness of Allah, Glorified and Exalted is He) and the concept of being brought back to life on the Day of Judgement after one was physically dead.
Thus, the verses whose axis rotates around the discussion of issues such as the origin (of life), Resurrection Day and the verses which reproach Polytheism and speak about the outcome of the previous generations that were inflicted with the anger and punishment of Allah (Glorified and Exalted is He) due to not following His commandments and their appointed Messengers, were most often revealed in Makkah. However the environment in Madinah was an atmosphere of faith, virtue and piety.
It was a centred where the Ahl al-Kitab - especially the Jews – had influenced and permeated into. It was an atmosphere of young men, heroes, champions and brave people who readily accepted the teachings of Islam.
