Quran 112:2-4: God is independent and everything else is dependent on him for their existance.
Quran: Ikhlaas (112:2-4)
Translation: Tafheem-ul-Quran - Abul Ala Maududi

Allah, Who is in need of none and of Whom all are in need;


He neither begot any nor was He begotten


and none is comparable to Him

ٱللَّهُ ٱلصَّمَدُ

لَمْ يَلِدْ وَلَمْ يُولَدْ

وَلَمْ يَكُن لَّهُۥ كُفُوًا أَحَدٌۢ

Reference  : Quran: Ikhlaas 112:2-4

Note: All creation has a point in time in which it came into existance. The universe came into existance by virtue of the Big Bang some 14 billion years ago. The elements in the human body were created within stars, everything began somewhere. Allah eloquently argues the fact that they came into existence necessitates there being something to bring them into existence with the will to bring them into existence. That being (himself), who by necessity, must be independent - not dependent on anything else for his existence. Only the independent could have manifested the dependent. He says all this so eloquently in just 2 words.
