فِى جَنَّـٰتٍ يَتَسَآءَلُونَ / عَنِ ٱلْمُجْرِمِينَ / مَا سَلَكَكُمْ فِى سَقَرَ
Fī jannātin yatasāʾalūn / ʿAni'l-mujrimīn / Mā salakakum fī saqar "They are in gardens, asking one another — about the guilty: 'What put you into saqar?'"
This form conveys reciprocity (mushāraka): taqātala (they fought one another), takhāṣama (they went to law with one another).
al-Nabaʾ opens with this verb (ʿamma yatasāʾalūn), and it was treated there.
The verse first says yatasāʾalūn — they ask one another; and the subject they ask about is ʿani'l-mujrimīn — about the guilty.
Then in the forty-second verse the question is directed straight at the guilty: mā salakakum — "what put you in?"
That is, the question passes from speaking about to asking directly. From the third person to the second.
Root: س-ل-ك. Its concrete sense: to pass a thing into another thing, to thread it through like a thread.
Salaka'l-khayṭa fi'l-ibra — he threaded the thread through the needle. It has nothing to do with the Turkish "silk" and "meslekî"; but "sülûk" (entering upon a path) and "meslek" (the path entered upon) do come from this root.
- "Thus do We thread it into the hearts of the guilty" (al-Ḥijr 15/12).
- "Put into it two of every kind" (al-Muʾminūn 23/27) — into the ship.
- "And He made broad ways in it for you, that you might walk in them" (Nūḥ 71/20).
- "Whoever turns away from the remembrance of his Lord, He will put him into a grievous punishment" (al-Jinn 72/17) — yasluk-hu ʿadhāban ṣaʿadā.
At al-Jinn 72/17 the same verb (salaka) and the same root (ص-ع-د, ṣaʿadā) occur side by side. And in this sūra too both are present: sa-urhiquhū ṣuʿūdā (74/17) and mā salakakum fī saqar (74/42).
Two words, in two sūras, in the same context. I record this as an observation; I make no claim of a reference.
And the verb is transitive: salakakum — "put you in". That is, the agent is being asked: what was the thing that put you in there?
The verse does not describe the state of the people of the Fire from outside; it makes them recount it in their own words. And this is one of the most effective techniques of the sūra.
