ذَٰلِكَ مَبْلَغُهُم مِّنَ الْعِلْمِ ۚ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِمَنِ اهْتَدَىٰ

“That is their extent of knowledge. No doubt, your Lord is most knowing of who has strayed from His way, and He is most knowing of who has followed guidance”.

ذَٰلِكَ مَبْلَغُهُم مِّنَ الْعِلْمِ Limited reach vs. comprehensive knowledge

Core message & themes

“That is their extent of knowledge” marks a limit to their thought, set by their intention to desire only this worldly life. Human agendas and thinking are influenced by emotions.

“No doubt, your Lord is most knowing…” affirms that Allah alone fully knows who has strayed and who is guided — encompassing outer claims and the inner reality of sincerity and intentions.

The phrase مَبْلَغُهُم (“their extent”) can imply a collective, societal limiting — a social standard that pressures individuals to conform to desiring the worldly life.

Language deep-dive

Precision of wording frames the meaning

مَبْلَغُ (Mablagh) — reach, extent, final limit

Root: from بَلَغَ (Balagha) — to reach/arrive.

  • بَلَغْتَ المَكان (Balaghta l-Makaan): “You have arrived at the place”.
  • التَّبْلِغَة (At-Tablighah): a rope extending the original rope on a bucket so it reaches the bottom of a well.
  • بَلَغَ النَبْت (Balagha n-Nabt): “The vegetation has completed its growth”.
  • بَالِغ (Baaligh): one who reaches puberty.
  • بِلْغ (Bilgh): negative sense — an underhanded, devious person who will use any means to “reach” goals (ends justify the means).

Form: مَبْلَغُ is a Zharf (adverb), indicating the final place that can be reached — the extent.

The demonstrative ذَٰلِكَ (Dhaalika) — precise reference

  • Masculine “that” signals it does not refer to the feminine الْحَيَاةَ الدُّنْيَا from the previous verse.
  • Possible references:
    • يُرِدْ (“they want”): their want is the extent of their knowledge.
    • Implied word (omitted): the “affair” (أَمْر) of the worldly life.
    • ظَنّ (assumption): the conjecture they follow.

Insight: their cognitive process is bounded by what their hearts desire. Earlier in the Surah: إِن يَتَّبِعُونَ إِلَّا الظَّنَّ وَمَا تَهْوَى الْأَنفُسُ — they follow assumptions based upon desires.

العِلْم with Laam al-Istighraaq — universality

  • The definite article denotes total inclusion — comprehensive, all-encompassing knowledge.
  • Read as knowledge embracing both the seen and unseen; material and immaterial.
  • Worldly knowledge, if not guided by true spiritual knowledge, is deficient and can lead to negative and dangerous results. When worldly knowledge is guided by true spiritual knowledge, it qualifies as العِلْم (complete knowledge).

Societal limiting — “their extent”

The expression مَبْلَغُهُم can imply a collective, societal ceiling: the standard of desiring the worldly life is set by society, creating pressure to conform Collective pressure Cultural norm

Limited knowledge vs. no knowledge

When some knowledge equals no knowledge

Previous statement

وَمَا لَهُم بِهِ مِنْ عِلْمٍ — “And they have no knowledge of it whatsoever”.

Here, “limited knowledge” may in effect equal “no knowledge” when it yields no benefit in the lived reality.

Illustration

يَعْلَمُونَ ظَاهِرًا مِّنَ الْحَيَاةِ الدُّنْيَا وَهُمْ عَنِ الْآخِرَةِ هُمْ غَافِلُونَ

They know only the outer appearance of the life of the world, and they are unmindful of the Hereafter (Ar-Rum: 30).

Guidance and misguidance — who knows best

Allah makes clear to His Prophet ﷺ that He knows better who is lost and who is guided. This judgment is not limited to outward ideas and claims; it includes what lies in the heart — sincerity and intentions known only to Allah.

Secondary meanings of ضَلَّ (Dalla — “to be lost”)

  • When two things appear as one — truth and falsehood are conflated to be the same (e.g., all religions studied merely as cultural-historical phenomena). This conflation is one meaning of ضَلَال (Dalaal).
  • To be “wasted” — e.g., the intellect diverted from pursuing the truth.
  • To be destroyed/brought to nothing — nullified, thwarted, made to be lost. Example:

    أَلَمْ يَجْعَلْ كَيْدَهُمْ فِي تَضْلِيلٍ

    Did He not make their plot come to nothing (Al-Feel: 2).

  • To be gullible — easily convinced, devoid of critical thinking.

Wants vs. knowledge — the heart-mind link

“Wants” relate to the heart, while عِلْم (knowledge) relates to the mind. They follow assumptions in line with desires: إِن يَتَّبِعُونَ إِلَّا الظَّنَّ وَمَا تَهْوَى الْأَنفُسُ.

Thus, “their want is the extent of their knowledge.” Their intention to desire the worldly life sets a limit on their thinking.

Rhetorical emphasis

Ibn ‘Āshūr on إِنَّ and repeated هُوَ

The use of إِنَّ (“No doubt/Indeed”) and repeating the separate pronoun هُوَ (“He”) adds emphasis, though the Prophet ﷺ has no need of such emphasis. This suggests a kinaayah (implied meaning): “He is more knowledgeable about their condition or state than you. You do not know what is inside of them, so do not be distressed (or in a state of grief) over them”.
