It is a project aimed at reminding people of this noble Sunnah, by accepting their sacrifices and performing the slaughter on their behalf, then distributing the meat to poor and needy Muslims.
The "Seventh" (As-Sub') in camels or cattle
(including calves) refers to the legal Shari'ah share that is sufficient for
one person as an Udhiyah (sacrifice). Jurists have determined that one cow or
calf is equivalent to seven individual sacrifices.
This is based on the Hadith narrated by Jabir bin Abdullah (may Allah
be pleased with him):
"In the year of Al-Hudaybiyyah, we sacrificed with the Messenger
of Allah ﷺ a camel for seven people and a cow for
seven people."
