Surah An-Najm — Ayah 28 (53:28)
وَمَا لَهُم بِهِۦ مِنۡ عِلۡمٍۖ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّۖ وَإِنَّ ٱلظَّنَّ لَا يُغۡنِي مِنَ ٱلۡحَقِّ شَيۡـٔٗا ٢٨
English translation (Saheeh International)
And they have thereof no knowledge. They follow not except assumption, and indeed, assumption avails not against the truth at all.
Brief commentary
In giving them female names they have no knowledge to base this on. They merely follow speculation. Speculation is of no value against the truth, to take its place.
