لَا يُقَٰتِلُونَكُمْ جَمِيعًا إِلَّا فِى قُرًى مُّحَصَّنَةٍ أَوْ مِن وَرَآءِ جُدُرٍۭ بَأْسُهُم بَيْنَهُمْ شَدِيدٌ تَحْسَبُهُمْ جَمِيعًا وَقُلُوبُهُمْ شَتَّىٰ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ
Lā yuqātilūnakum jamīʿan illā fī quran muḥaṣṣanatin aw min warāʾi judur, baʾsuhum baynahum shadīd, taḥsabuhum jamīʿan wa qulūbuhum shattā, dhālika bi-annahum qawmun lā yaʿqilūn
"They will not fight you all together except in settlements protected by walls or from behind walls. Their violence among themselves is severe. You would think them united, whereas their hearts are scattered. That is because they are a people who do not use their reason."
قُرًى مُّحَصَّنَة — "settlements protected by walls". The root ح-ص-ن is the same as that of ḥuṣūn (fortresses) in the second verse.
The sūra brings the same root a second time. And the two occurrences say the same thing: leaning upon a defensive structure is recorded as a sign not of strength but of weakness.
The concreteness of the word matters. The verse is not making a strategic military assessment; it is drawing a picture: men are standing behind a wall and fighting from there.
What does it say? Making a defence is not blamed — every army makes a defence. What is blamed is being able to fight only from behind a defence: the particle illā (except) marks this. That is, there is no other option.
And this is not a problem of capacity but a problem of unity. To fight in the open requires trust between the ranks. A man who is not sure that the one beside him will not run does not stand in the open.
بَأْس — Root: ب-أ-س. The field of meaning of this root in Arabic is wide, and all of it points to a hardness: baʾs (fighting strength, violence, hardship), baʾsāʾ (distress, poverty), bāʾis (severe), biʾsa (how evil!).
At al-Baqara 2/177, where three states of patience are enumerated, two of them came from this root: baʾsāʾ (poverty) and ḥīna'l-baʾs (the moment of fighting).
The word order of the sentence is meaningful: baʾsuhum baynahum shadīd — "their hardness is severe among themselves". Baynahum has been put in between and carries the emphasis.
That is, the strength is not lacking; its direction is wrong. The hardness that cannot be used against the outside is being used inside.
This is the classic description of a community coming apart, and it is seen at every scale: groups that scatter in the face of an outside threat are most of the time extremely sharp inside. The energy is not lost, it changes direction.
تَحْسَبُهُمْ — Root: ح-س-ب. To count, to reckon, to suppose. This root occurs in the sūra for the second time (the first at 59/2: lam yaḥtasibū).
And in the second verse it was they who reckoned wrongly; here the danger of reckoning wrongly is in the one addressed: "you would think them united." The address is singular and direct.
جَمِيعًا — "united, together". This word circulates in this sūra and in the preceding one: at al-Mujādala 58/6 and 58/18, "God will raise them all" (a real gathering); here, a false appearance of unity.
شَتَّىٰ — Root: ش-ت-ت. Scattering, dispersal, falling apart from one another. Shattā is the plural of shatīt: "scattered, separate".
In the Qurʾān: "After that people will come forth in separate groups" (al-Zilzāl 99/6); "Your striving is various and separate" (al-Layl 92/4). Both occurred in this commentary.
And the verb matters: taḥsabuhum — "you would think". That is, the appearance really is one of unity. The verse does not belittle the other side; it says that the appearance is deceiving.
This verse gives the measure of whether a community really is a community: not the number of bodies, but the state of the hearts.
And this connects directly with the notion of ḥizb in Sūrat al-Mujādala. There the root of ḥizb was "to gather around a common business". Here a crowd with no common business is described: they are standing side by side but they are not together.
"Had you spent all that is in the earth, you could not have joined their hearts together. But God joined them." — لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ (al-Anfāl 8/63)
At al-Anfāl 8/63 all the wealth of the world is not enough to join hearts. At al-Ḥashr 59/14 it is said that a community whose hearts are not joined cannot fight, however numerous it may be.
And this connects quietly with the section of the sūra on the division of the fayʾ: property does not keep a community standing. The division in verse 7 regulated the circulation of property; verse 9 praised īthār; verse 10 asked for the tearing out of the rancour in the heart. What is being built throughout the sūra is not the distribution of property but the state of the hearts.
