How can ye reject the faith in Allah? Seeing that ye were without life and He gave you life; then will He cause you to die and will again bring you to life; and again to Him will ye return.

Al-Baqara (2:28)

Be sure We shall test you with something of fear and hunger some loss in goods or lives or the fruits (of your toil) but give glad tidings to those who patiently persevere.

Al-Baqara (2:155)

Who say when afflicted with calamity: "To Allah we belong and to Him is our return."

Al-Baqara (2:156)

It is Allah who creates you and takes your souls at death; and of you there are some who are sent back to a feeble age so that they know nothing after having known (much): for Allah is All-Knowing All-Powerful.

An-Nahl (16:70)

Every soul shall have a taste of death: and We test you by evil and by good by way of trial: to Us must ye return.

Al-Anbiyaa (21:35)
