Is it a condition for the Aqiqah or Udhiyah that it be distributed into three parts, or is it permissible for the sacrificer to keep all the meat, or to donate all of it, or to make a feast with it?

The jurists have recommended dividing the sacrifice (Udhiyah) and the Aqiqah (sacrifice for a newborn) into three parts: one-third for eating, one-third for feeding, and one-third for charity, based on the narrations of Abdullah and Ibn Abbas. Some jurists are of the opinion that it should be divided into two halves. As for the Aqiqah, it is permissible to divide it into three parts or two halves, or to eat it all, or to give it all in charity, or to make a feast. The most preferable is to eat from it and give some in charity.
