Please provide the related Hadith for the first question. For the third question, can we do a single sacrifice and request Allah s.w.t. to forward the Sawaab to all our Marhoomeen or do we need to do one sacrifice for each relative? Would this Isaal-e-Sawaab be any different than forwarding the reward for reading Qur?an or doing acts of charity? If so, why?
Answer:
In principle, when offering Nafl Qurbaani, one may make one, two or multiple intentions.
Therefore, if a Nafl sacrifice you intend for Rasulullah [Sallallahu Alayhi Wasallam] and family members, it will be valid.
and Allah Ta’ala Knows Best
