Sahih Muslim 2280

Jabir reported that Umm Malik used to send clarified butter in a small skin to the Messenger of Allah (ﷺ). Her sons would come to her and ask for seasoning when they had nothing with them (in the form of condiments) and she would go to that (skin) in which she offered (clarified butter) to Allah's Apostle (ﷺ), and she would find in that clarified butter and it kept providing her with seasoning for her household until she had (completely) squeezed it. She came to Allah's Apostle (ﷺ) and (informed him about it). Thereupon, he (the Holy Prophet) said:Did you squeeze it? She said: Yes. Thereupon he said: If you had left it in that very state, it would have kept on provid- ing you (the clarified butter) on end
