Inna kulla shay-in khalaqnahu biqadar (surah Al Qamar: 49)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(54:49) We have created everything in a determined measure. *25

Innaa kulla shai`in khalaqnaahu biqadar

*25) That is, 'Nothing in the world has been created at random but with a purpose and destiny. A thing comes into being at an appointed time, takes a particular form and shape, develops to its fullest extent, survives for a certain period, and then decays and dies at an appointed time. Even according to this universal principle this world too has a destiny in accordance with which it is functioning till an appointed time and will come to an end at an appointed tune. It will neither come to an end a moment earlier than its appointed time of end nor survive a moment longer; it has neither existed since eternity nor will exist rill eternity, nor is it the plaything of a child which he may destroy as and when he likes."
