What is the reason for the revelation of some surahs of the Holy Quran in Mecca and other surahs in Medina?

The Holy Quran was revealed in Mecca and Medina, and its miraculous nature lies in its words, meanings, eloquence, clarity, and impact on hearts, not in the place of its revelation. The reason some surahs were revealed in Mecca and others in Medina is due to the Prophet's migration (peace and blessings be upon him) from Mecca to Medina, which led to a shift in the place where revelation descended.
