Piety

Piety is a great virtue that bears a lofty status. It sustains life, which becomes unbearable in its absence; in fact, a life void of piety is inferior even to the life of an animal. There is no righteousness and wellbeing for a slave without Taqwaa (piety). It is a noble treasure whose possessor is awarded many honorable gems, abundant goodness, noble sustenance, great victories and kingdoms. It is as if the best rewards of both this 

life and the next have been assigned to this single characteristic!
