The Messenger of Allah (may Allah's peace and blessings be upon him) used to strive during the last ten more than he would strive at any other time

Upon reaching the last ten nights of Ramadan, the Prophet (may Allah's peace and blessings be upon him) used to exert himself in performing acts of worship and acts of obedience. He used to exaggerate in offering various types of good deeds, different forms of acts of benevolence, and acts of worship more than he would offer at any other time, given the greatness and merit of such nights and seeking the Night of Decree.
