If an animal is sacrificed by more than one person, like cow or camel, its meat should be distributed equally among its owners by weighing the meat strictly and not at random or by mere guess. Even if all the partners agree on its distribution without weighing, it is still not permissible according to shari’ah.
However, if the actual weighing is not practicable due to some reason, and all the partners agree to distribute the meat without weighing, distribution by guess can be done with the condition that each share necessarily contains either a leg of the animal or some quantity of its liver.
Although the person offering a Qurbani can keep all its meat for his own use, yet, it is preferable to distribute one-third among the poor, another one-third among his relatives and then, keep the rest for his personal consumption.
All parts of the sacrificed animal can be used for personal benefit, but none can be sold, nor can be given to the butcher as a part of his wages. If somebody has sold the meat of the Qurbani or its skin, he must give the accrued price as sadaqah to a poor man who can receive Zakah.
