Is money earned from selling a calf that died before its ritual slaughter, knowing that the slaughterer informed the buyer of its death before the sale, unlawful or lawful?

If the calf in question did not move after it was slaughtered, and its blood flowed without force, then it is carrion (maytah), and its sale and purchase are prohibited, based on the Prophet's (peace be upon him) saying: "Indeed, Allah and His Messenger have forbidden the sale of intoxicants, carrion, swine, and idols." Repentance is obligatory, and the money earned from it must be given in charity. The buyer should also be advised to give in charity what he paid. However, if the blood flowed with force and vigor, as is customary, then the calf is lawfully slaughtered (dhakat shari'ah), and the price earned from it is permissible.
