Abu Hurairah reported,

The Messenger of Allah ﷺ said, "Shall I tell you of what Allah uses to wipe away sins and raise ranks?"They said, "Yes indeed, Messenger of Allah."He said, "Performing wudu thoroughly despite hardships, taking many steps to the mosques, and waiting for the next prayer after the prayer. That is the true vigilance."In Qutayba's version of the hadith, he said, "That is the true vigilance, that is the true vigilance, that is the true vigilance," three times.
