وَمَا تَخْرُجُ مِن ثَمَرَٰتٍ مِّنْ أَكْمَامِهَا وَمَا تَحْمِلُ مِنْ أُنثَىٰ وَلَا تَضَعُ إِلَّا بِعِلْمِهِۦ
"No fruit comes out of its sheath, and no female conceives or gives birth, save with His knowledge."
أَكْمَام — singular kimm: the sheath in which a fruit or a flower sits, the envelope of the bud. Root ك-م-م: to cover, to close over. The cuff of a garment — the opening at the sleeve — is linked to this root as well, and Turkish, which borrowed the word, ties its kem to the same root. English has no such link: husk and cuff are two unconnected words.
The word occurred at al-Raḥmān 55/11 (wa'n-nakhlu dhātu'l-akmām) and was treated there. I do not repeat it here.
The choice of the two examples is worth recording: the fruit's coming out of its sheath, and birth. Both describe a coming out from an enclosed place — and both become visible at the end of a process that is not seen.
I record this as my own reading: the verse describes the scope of the knowledge by way of the most hidden processes. And this stands exactly opposite the supposition in the twenty-second verse — there it had been supposed that "He does not know much of what we do".
