Bismillahir rahmanir rahim.

Zaid bin Arqam RadiAllahu Anhu se rivayat hay ki Sahabae kiram ne Allah ke Rasool Sallallahu Alayhi Wa sallam se pucha:

“Is (Qurbani) se hame kya faeda pahuche ga? Aap Sallallahu Alayhi Wa sallam ne Jawab diya, Badla (Inaam) hay har Ball ke Zarre aur Oon ke reshe ke barabar”.

It is also narrated from Zaid bin Arqam, that the companions asked the Prophet Sallallahu Alayhi Wa sallam:

“What benefit do we get from it (sacrifice)?” He answered, a reward for every grain of hair or fibre of wool”.
