It is narrated by Hazrat Abdullah Bin Abbas رضی اللہ عنہ that Prophet ﷺ said that whoever sacrifice one animal with pure intention in way of Allah, he will get so much reward whose counting is also not even known by the angles of Allah جل جلالہ. So the first reward of sacrifice is this that the
first drop that fells on ground, in its reward, the one doing sacrifice gets 70 statuses. In change of 2nd drop, he gets 70 good deeds. In return of
3rd drop, his 70 sins are been erased and on
4th drop, the air which comes out of his mouth saying takbeer, that will be fragrant to Allah more than musk.
On 5th drop, his tongue and whole body will be such cleaned from sins, as if he has just born from the stomach of his mother.
On 6th drop, city will be made ready for him in heaven.
