Ibn 'Umar narrated that the Messenger of Allah said: "There shall be upon dunes of musk- I think he said: On the Day of Judgment- a slave who fulfills Allah's right and the right of his patron (master), a man who leads a people (in prayer)) and they are pleased with him. And a man who calls for the five prayers during every day and night"
