Ahsanallahu ilaykum ustadh, is it valid to take part in Udhiya (slaughter/distribution/etc.) if the family is in debt but plans to repay later and has enough assets to cover it? My father joined a meat share using his Eid pension allowance—does this affect validity?

Ustadh AbdulAziz al-Haqqan
If he knows he is capable of paying the debt in time then it is fine in sha'a Allah as mentioned by Imam Ibn Uthaymeen otherwise he shouldn't.
