True piety is this : to believe in God , and the Last Day , the angels , the Book , and the Prophets , to give of one 's substance , however cherished , to kinsmen , and orphans , the needy , the traveller , beggars , and to ransom the slave , to perform the prayer , to pay the alms . And they who fulfil their covenant when they have engaged in a covenant , and endure with fortitude misfortune , hardship and peril , these are they who are true in their faith , these are the truly godfearing .
