It was narrated that 'Aishah said: " "Some Bedouins came to Al-Madinah at the time of (Eid) Al-Adha and the Messenger of Allah (ﷺ) said: 'Eat, and store (the meat) for three days.' After that they said: 'O Messenger of Allah, the people used to benefit form their sacrifices by melting down the fat, and (also) making water skins from them.' He said: 'Why are you asking?' He said: 'Because you forbade us form keeping the meat of the sacrificial animals.' He said: 'I only forbade that because of the Bedouins who came. (Now) eat it, store it and give it in charity," (Sahih )
