Is it permissible for an unmarried employee who does not live with his parents to buy the Eid sacrifice on behalf of his father, or must the father sacrifice from his own money? Is it permissible to give some money to the father to help him buy the sacrifice? And must the son offer a sacrifice on his own behalf, given that he is single and able to do so?

Scholars have agreed that a man's sacrifice (Uḍḥiyah) on behalf of himself and his household suffices for them as a communal obligation (Sunnat al-Kifāyah), based on the Hadith of Abu Ayyub al-Ansari (may Allah be pleased with him). Scholars have differed on defining "household" (Ahl al-Bayt) into four opinions: those who meet the conditions of financial support, kinship, and cohabitation (Malikis); or those who share a single provider's expenses (some later Shafi'is); or all of the sacrificer's relatives; or those who live with him, even if they are not relatives (some later Shafi'is).

The ruling concluded that a son living in a separate house from his father should offer his own sacrifice, and his father's sacrifice does not suffice for him, because he is not considered part of the father's household in this case. If he donates money to help his father with the cost of the sacrifice, he will receive the reward for donation and charity, but not the reward for the sacrifice itself.
