Surah Al-Kahf 18:4
سُورَةُ الكَهۡفِ · Meccan · Verse 4 of 110
وَيُنذِرَ ٱلَّذِينَ قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًا
Translation
It warns those people who assert, ‘God has offspring.’
English translation: M.A.S. Abdel Haleem.
Meaning and reflection
'And to warn those who say God has taken a son.' Ibn Ashur and al-Saadi note the Book's straightness confronts the gravest crookedness of all, the claim that God has offspring, attributing to the Absolute a need, a lineage, a limit. Ask yourself: I may not literally say God has a son, but I have my own subtler ways of dragging Him down to my scale, imagining Him as needing my worship, moved by the same pettiness I feel, bound by the logic I understand. This verse defends His utter transcendence. It presses me to examine the small, false 'sons' I attach to Him, the ways I quietly shrink the Infinite into something manageable and human-sized, so I don't have to reckon with One who is truly beyond me.

Wording
Surah Al-Kahf begins with praise for Allah, who sent down the Quran to His servant Muhammad, a perfect Book free from distortion. It serves to warn against a severe punishment and to give glad tidings of a good reward. Then, in verse 4, Allah specifically focuses the warning:
The Distinct Warning
This verse, "And to warn those who said, 'Allah has taken a son'," (Surah 18:4, `وَيُنذِرَ ٱلَّذِينَ قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًۭا`), is an additional purpose for the revelation of the Quran. It follows a general warning in a previous verse, but by repeating the verb `يُنذِرَ` (warns) here, Allah singles out a particular group and a particular claim as exceptionally grave. As al-Razi explains, it highlights that claiming Allah has an offspring is among the most heinous forms of disbelief. The Quran directly names these people by their egregious statement, `الَّذِينَ قَالُوا اتَّخَذَ اللَّهُ وَلَدًا` (those who said Allah has taken a son), rather than a general descriptor. Ibn Ashur notes this specific phrasing is a form of vilification, powerfully identifying them by the very falsehood that makes them deserving of this severe warning. The word `وَلَدًا` (offspring or child) in Arabic is comprehensive, covering any type of issue, male or female, singular or plural.
No Basis, No Knowledge
The verse then immediately states, "They have no knowledge of it" (`مَا لَهُمْ بِهِ مِنْ عِلْمٍ`). The particle `مِنْ` (min) before `عِلْمٍ` (knowledge) acts as an intensifier, emphasizing a complete and absolute lack of knowledge about this claim. As al-Zamakhshari clarifies, it means their assertion is not based on any factual understanding; it stems from profound ignorance. The pronoun `بِهِ` (of it) refers to the very act or concept of Allah taking a son, indicating they have no true understanding or evidence for such a monumental claim. Furthermore, Allah adds, "nor their forefathers" (`وَلَا لِآبَائِهِمْ`). This is a crucial addition, according to Ibn Ashur, as it dismantles one of their primary arguments: blind imitation of ancestors. It highlights that this grave falsehood has no foundation whatsoever, neither from themselves nor from those they follow.
The Weight of a "Word"
The enormity of their statement is then underscored with, "Grave is the word that comes out of their mouths" (`كَبُرَتْ كَلِمَةً تَخْرُجُ مِنْ أَفْوَاهِهِمْ`). The verb `كَبُرَتْ` (it became grave or enormous) conveys a sense of astonishment and severe condemnation. Al-Razi points out that while `كَلِمَةً` (a word) is singular, it refers to the entire statement "Allah has taken a son." This choice of a singular "word" emphasizes the profound weight and sheer magnitude of this single declaration of falsehood. The phrase `تَخْرُجُ مِنْ أَفْوَاهِهِمْ` (that comes out of their mouths) further intensifies the condemnation. Al-Zamakhshari observes that people often harbor wicked thoughts internally, but to actually *utter* such a horrific fabrication about Allah shows an audacious disrespect and profound moral failing. It is a lie so repugnant that even the mind should reject it, yet their tongues brazenly pronounce it.
