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
