In the next verse: وَمِن كُلٍّ تَأْكُلُونَ لَحْمًا طَرِيًّا وَتَسْتَخْرِجُونَ حِلْيَةً تَلْبَسُونَهَا (And from each, you eat fresh meat, and derive ornaments that you wear - 35:12), it is being said that one gets fresh meat, that is, fish to eat from both waters, sweet or brackish. In this verse, by alluding to fish as meat, the hint released is that fish is meat, already halal by itself. One does not have to slaughter it. This is contrary to the case of the animals found on land. Unless one slaughters them with the name of Allah, they do not become halal. Fish does not have this condition. It is meat, ready to eat. And the word: حِلْيَةً (hilyah) means ornament and refers to pearls. The verse tells us that the way pearls are found in brackish waters, they are also found in sweet waters, something contrary to the general belief, since it is well known that pearls are harvested from the brackish water of the seas. However, the reality is what is evident from the words of the Qur'an that they form in both - yes, much less in sweet waters and far more in the brackish waters of the sea. That they are found in seas excessively contributed to the popular belief that pearls come only from brackish waters.
By using the masculine form in the last word: تَلْبَسُونَهَا (talbasunaha: that you wear), a hint is being released that the use of pearls is permissible for men as well - contrary to gold and silver, the use of which as an ornament is not permissible for men. (Ruh-ul-Ma’ ani)
