The excellence of sacrificing an animal
There are many Hadith which describe the excellence of sacrificing an animal and its rules. On the day of Eid Ul Azha, the deed most loved by Allah Most High is sacrificing the animal. The blood of the animal is accepted by Allah Most High before it falls on the ground. Thus, we should perform this act wholeheartedly with a good intention. There is a Hadith in Jame’ Tirmidhi:
The mother of the believers, Hadhrat Aisha Siddiqua (May Allah be well pleased with her) narrates that Holy Prophet (Sallallahu alaihi wa sallam) said: On the day of sacrifice, no other deed of a man is more liked by Allah Most High than the shedding the blood in sacrificing the animal and undoubtedly, on the Day of Judgment, the animal will come along with the horns, hairs and hooves. The blood of the sacrificed animal is accepted in the court of Allah Most High before it falls on the earth. Thus you should sacrifice an animal wholeheartedly.
