يَعْلَمُونَ yaʿlamūna they will know

Tafsir Ahsan al-Bayan is a well-known Quran commentary by Hafiz Salahuddin Yusuf, a renowned Salafi (Ahl al-Hadith) scholar from Pakistan. This tafsir explains the meanings of the Quran in accordance with the methodology of the Salaf (early righteous generations), relying on authentic sources and straightforward language. Due to its reliability and adherence to sound Islamic scholarship, the Saudi government publishes and distributes this tafsir among the Hujjaj (pilgrims) visiting the Haramain. The tafsir is originally written in Urdu, translated to English by tohed.com.

66-1 This "laam" is *kayy*, which is for causation. That is, after being saved, their associating partners is so that they may be ungrateful for the favor and continue to enjoy the pleasures of the world. Because if they were not ungrateful, they would remain steadfast upon sincerity and would always call upon Allah alone. Although their intention is not to disbelieve, the result of committing shirk again is disbelief nonetheless.
