Wa alaykum assalamu warahmatullah,

In the Name of Allah, the All-Merciful, the Mercy-Giving

All praise is due to Allah alone; peace and blessings be upon Our Prophet Muhammad.

The Prophet (peace and blessings be upon him) is reported to have said, “Whoever has slaughtered a sacrificial animal should not keep anything of its meat beyond three days.” When it was the following year the people said, “O Allah’s Messenger! Shall we do as we did last year?” He (peace and blessings be upon him) said, “No, in that year the people were having a hard time and I wanted you to help [the needy].” This hadith along with many other narrations indicate that the Prophet (peace and blessings be upon him) forbade Muslims to preserve the meat of Udhiyah, but later he declared it permissible. This means that the forbiddance of preserving the meat of Udhiyah was abrogated as believed by the majority of scholars.

Allah Almighty knows best.
