Have they not reflected that God created the heavens and the earth and everything between them for a worthy end and for a fixed term? Yet many people deny that they will ever meet their Lord.
(Qur'an, 30: 8)
Everyone in the world went into his mother's womb as a simple sperm cell and there, under specially created conditions, united with an egg. After this, he began life as a single cell. You also went through this process along with your mother, father, brothers and sisters, friends and acquaintances and people you don't even know. Not only those who are alive now, but everyone from the first human being to members of the present generation, have undergone the miraculous stages described in this book.
During those months when the growing embryos had not even the slightest awareness of their existence, God gave form to their bodies and created each one as a whole human being from one single cell. It is the duty of everyone who lives on the face of the earth to consider this truth...
And it is your duty to think about how you came to exist, and to be grateful to God Who created you. Do not forget that the Lord Who created your body once will create it once again when you die and will demand a reckoning.
This is very easy for God, the Owner of eternal power.
However, those who forget their creation and deny God and the Day of Judgement are heedless in the extreme. In the Qur'an, God refers to them in this way:
Does not man see that We created him from a drop, yet there he is, an open antagonist! He makes likenesses of Us and forgets his own creation, saying, "Who will give life to bones when they are decayed?" Say "He Who made them in the first place will bring them back to life. He has total knowledge of each created thing." (Qur'an, 36: 77-79)
