Can members of a happy household buy the sacrificial animal together even if any one of them is not financially capable?
assalaam o alaykum
The offering is not compulsory for those who don't afford it. However, it must remain clear a single qurbani is to be done by a single person if the animal is like goat etc. If the animal offered is the kind of camel, cow etc. then seven people can join. If you plan to buy sheep or goat jointly it would be on behalf of a single person. This is ritualistic element of the matter. God knows our intentions and He knows how we all participated. Therefore, all the participants can hope to earn equal reward.
