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!

Allah takes the souls at the time of their death, and those that die not during their sleep; then He withholds those on whom He has passed the decree of death and sends the others back till an appointed term; most surely there are signs in this for a people who reflect.
