Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Whoever would be pleased to meet Allah tomorrow as a Muslim, let him guard these five prayers at the time the call (adhan) is made for them, for they are among the ways of guidance." Then he mentioned the rest of the hadith like the hadith of al-Mas'udi.
