Surah Az-Zukhruf — Ayah 15 (43:15)
وَجَعَلُواْ لَهُۥ مِنۡ عِبَادِهِۦ جُزۡءًاۚ إِنَّ ٱلۡإِنسَٰنَ لَكَفُورٞ مُّبِينٌ ١٥
English translation (Saheeh International)
But they have attributed to Him from His servants a portion.1 Indeed, man is clearly ungrateful.
- - By claiming that He (subḥānahu wa taʿālā) has a son or daughters, as it is said that a child is part of his parent. This concept is totally incompatible with Allāh's unity and exclusiveness.
Brief commentary
The idolaters claim that some of the creations are the offspring of the Creator (may He be glorified), when they said, “The angels are the daughters of Allah”. Indeed, the human who makes these kind of statements is very ungrateful and deviant.
