Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) said: The Prophet (peace and blessings be upon him) sent out a detachment; they took spoils and returned quickly. People began to talk about how near their expedition was, how plentiful their spoils were and how quickly they returned. Thereupon the Prophet (peace and blessings be upon him) said: "Shall I not tell you of something with an even nearer expedition, more spoils and a quicker return? Whoever performs ablution and then goes to the mosque for the morning prayer, his is the nearest expedition, the greatest spoils and the quickest return."
