multiplied rewards

The Messenger of Allah ( may the peace and blessings of Allah be upon him ) said: "A man's prayer in congregation is twenty-five times more rewarding than his Salat at home or in his shop, Abdullah ibn Umar ( May Allah be pleased with him ) narrated that the Messenger of Allah ( may the peace and blessings of Allah be upon him ) said, "Prayer in congregation is better than the prayer of a man by himself by twenty-seven degrees."

“If anyone calls the adhan for twelve years, paradise is guaranteed to him; sixty blessings will be recorded for him for every day’s calling of the adhan and thirty blessings for every iqama.”
