Our being able to wake up in the morning is a great miracle. Despite having lost consciousness entirely, in the morning we recover consciousness and our personalities. The heart beats, we are able to breathe, talk and see. In fact, when we go to sleep, there is no guarantee that these favours will be returned to us in the morning. Nor have we met any disasters during the night. For example, the absent-mindedness of a neighbour could cause a gas leakage and great explosion during the night could have woken us. A catastrophe could have occurred in the region where we lived and we could have lost our lives. Thinking on all of this, we thank Allah for His mercy and protection.
…My Lord, keep me thankful for the blessing You have bestowed on me and on my parents, and keep me acting rightly, pleasing You, and admit me, by Your mercy, among Your righteous slaves. (Surat an-Naml: 19)
