Is it not (the case) that to God belongs whatever is in the heavens and on earth? Is it not (the case) that God's promise (of the Day of Judgment) is assuredly true? Yet most of them understand not. It is He Who gives life and who takes it, and to Him shall you all be brought back. O mankind! there has come to you a direction from your Lord God and a healing for the (diseases) in your hearts,- and for those who believe, a guidance and a Mercy. Say: "In the bounty of God. And in His Mercy,- in that let them rejoice": that is better than the (wealth) they hoard. (The Holy Quran, 10:55-58)
