Merits Of Udhiyyah (Qurbani)
Our Prophet (Sallallâhu Alayhi Wa Sallam) said:
“The Day of Nahr (10th of Dhul-Hijjah) is one of the greatest days with Allah.”
“Offer sacrifice and treat the sacrificial animals gently. Indeed, if a person lays his sacrificial animal towards Qiblah and slaughters it, its blood and wool will be two fortresses to protect him on the Day of Qiyamah. Verily, the blood of the animal will fall on the ground under the protection of Allah. You will achieve plenty of rewards with a little spending (for Qurbani).”
Whoever approaches his sacrificial animal on the day of Nahr to slaughter it, Allah’s mercy will also approach (bless) him in Jannah. At the time of slaughter, Allah Ta‘ala forgives him with the first drop of the blood. Allah Ta‘ala will make that animal a ride for that person from the grave to the plains of Mahshar, rewarding him as much as the skin and the fibre of the animal.”
It is recommended for those who have the means to offer a sacrifice for the pleasure of Allah, on behalf of Rasûlullâh (SAW) and to earn the Shafa’ah (intercession) of Rasûlullâh (SAW).
Ali Al-Murtadha (Karramallahu Wajhahu) used to offer two rams, one for himself and one for Nabi (SAW), saying “Rasullulah (SAW) left me a will to offer Udhiyyah for his beloved personality.”

"It's neither their meat nor their blood that reaches Allah, but it is piety from you that reaches Him." (Quran, 22:37)
