And surely among you is he who would certainly hang back! If then a misfortune befalls you he says: Surely Allah conferred a benefit on me that I was not present with them.

And strive hard in (the way of) Allah, (such) a striving a is due to Him; He has chosen you and has not laid upon you an hardship in religion; the faith of your father Ibrahim; He named you Muslims before and in this, that the Messenger may be a bearer of witness to you, and you may be bearers of witness to the people; therefore keep up prayer and pay the poor-rate and hold fast by Allah; He is your Guardian; how excellent the Guardian and how excellent the Helper!
