From Sahih Bukhari (Hadith 5593):
Narrated `Abdullah bin `Amr:When the Prophet (ﷺ) forbade the use of certain containers (that were used for preparing alcoholic drinks), somebody said to the Prophet (ﷺ) . "But not all the people can find skins." So he allowed them to use clay jars not covered with pitch
