The fetus can hear while in the womb and is familiar with the sound of its mother’s heart and even her voice. The mention of these three invaluable favours motivates us to seek knowledge of the One Who has granted them to us. Some of the scholars of religion say that such knowledge leads us to thanking Him for these gifts, which is the basis for the rational obligation of knowing Allah.
The next verse speaks of one of the most important signs of Allah, which is the creation of man from the earth: “And He it is Who multiplied you in the earth...” And, because the human being is made of earth, he will return to it, and will be raised up and then will be mustered unto Him.

(“.. .Have you then no sense?”) After speaking about the proliferation of human beings, the Qur’an turns to the issue of life, death, and the alternation of day and night which are of the great signs of Allah. It says: “And He it is Who gives life and death, and to Him belongs the alternation of the night and the day.
Have you then no sense?” Thus, these recent three verses start with motivating us to know Allah and then end with mentioning some of the most important signs in the microcosm and the macrocosm. In other words, they mention man’s journey from birth to death and his return to Allah, all of which, are at the mercy of Allah and decided by His will.
The alternation of day and night means that one of them takes the place of the other.
