The dissemblers’ trade is pure evil and undiluted harm. Ascribing the verb to the trade here resembles the saying: “Nāma layluhu (his night slept)” instead of “nāma fi’l-layl (he slept in the night).” The former means that besides himself sleeping, the night was hushed and silent as though sleeping, and nothing disturbed him.
“And they are not rightly-guided (wa mā kānū muhtadīn):” that is, just as they have lost their capital, so have have they lost their way.

It also hints obliquely at “guidance for those who fear Allah (hudan li’l-muttaqīn)” at the start of the sura, as though it is saying: “The Qur’an offered them guidance, but they did not accept it.”
