Which is more befitting: giving 'Eidiya or offering a sacrifice, if one is unable to do both?

"Eidiya" (عيديه - a monetary gift given on Eid) is a permissible financial gift; it is not obligatory. It strengthens affection and endears children to the Eid celebration. Do not compare Eidiya to the Udhiyah (definition) (أضحية - sacrifice), which is one of the greatest rituals of the religion. Eidiya usually consists of symbolic amounts that do not affect one's ability to purchase the Udhiyah. If there is a conflict between the two, purchasing the Udhiyah takes precedence.
