Perform Hajj and ‘Umrah in succession, for they expel poverty and sins just as the bellows expels impurities from iron, gold, and silver. There is no reward for an accepted Hajj except Paradise

The Prophet (may Allah's peace and blessings be upon him) encouraged performing the rituals of Hajj and the rituals of ‘Umrah in close succession without interruption, as long as one is able. This is because performing them serves as a means to remove poverty and sins, as well as their effect on the heart, just as blowing the bellows removes impurities and other metals from the iron.
