Man La Yahduruhu al-Faqih, Vol. 2, p. 488

A man asked Imam Sadiq (peace be upon him) about sacrificing an animal. The Imam said: This act is obligatory upon every Muslim except for those who are financially unable.

The person asked: What about one's family (wife and children)? (Should I sacrifice on their behalf as well?)

The Imam said: If you wish, do so, and if you wish, do not. However, do not neglect it for yourself.

Al-Faqih, Vol. 2, p. 488

Imam Baqir (peace be upon him) said: The sacrifice of Eid al-Adha is obligatory upon whoever has the financial ability, whether it is small or large, and it is a Sunnah!

Al-Kafi, Vol. 4, p. 487

Imam Sadiq (peace be upon him) was asked about the sacrifice of Eid al-Adha, whether it is obligatory for a person who has the financial ability for himself and his family. The Imam said: As for himself, he should not neglect it, but for his family, if he wishes, he may neglect it!

3⃣عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ: سُئِلَ عَنِ الْأَضْحَی أَ وَاجِبٌ هُوَ عَلَی مَنْ وَجَدَ لِنَفْسِهِ وَ عِیَالِهِ فَقَالَ أَمَّا لِنَفْسِهِ فَلَا یَدَعُهُ وَ أَمَّا لِعِیَالِهِ إِنْ شَاءَ تَرَکَهُ.
