With the start of the ten, the Messenger of Allah (may Allah's peace and blessings be upon him) would revive the night, wake up his family, exert himself, and tighten up the lower garment

Upon the start of the last ten days of Ramadan, the Prophet (may Allah's peace and blessings be upon him) would revive the whole night with various acts of obedience. He would wake up his family to pray. He would exert himself in worship more than he usually did, and he would devote himself entirely to worship and avoid having intimate relations with his wives.
