The 10th day of the month marks the Eid al-Adha(Festival of Sacrifice). Even for those who are not traveling for the pilgrimage, this is a special time to remember Allah and spend extra time in devotion and good deeds. Muslims sacrifice cattle in memory of Prophet Ibrahim (As) , who was ready to sacrifice his son Ismail (As), at the command of Allah. The sacrifice is divided into three parts, one for the family, one for relatives and friends, and one for the poor. The real thing is in the spirit of piety and submission of Allah which this act expresses.
May Allah bless you all.
