You are talking about animal sacrifices, which are an act of worship and is supposed to be dedicated to Allaah only. Animal sacrifice is definitely a way to atone for sins, just like fasting, or giving charity, etc.
Hebrews 10:4 For
it is not possible that the blood of bulls and goats could take away sins.
However, in Islaam there is no such thing as "human sacrifice", as this is a pagan practice of various pagan cultures, which God in the Old testament considered as an abomination and way of the pagan gentile cultures which the Israelites were forbidden to follow their ways. For example, the pagans used to sacrifice humans to their idol molech. The Aztecs also sacrificed humans to their "gods".
Christians would agree that "human sacrifice" would be pagan, but we read:
Eph. 1:3 Blessed
be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly
places in Christ, 4 just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, 5 having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, 6 to the praise of the glory of His grace, by which He made us accepted in the Beloved. 7 In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace 8 which He made to abound toward us in all wisdom and prudence, 9 having made known to us the mystery of His will, according to His good pleasure which He purposed in Himself, 10 that in the dispensation of the fullness of the times He might gather together in one all things in Christ, both[
a] which are in heaven and which are on earthin Him. 11 In Him also we have obtained an inheritance, being predestined according to the purpose of Him who works all things according to the counsel of His will, 12 that we who first trusted in Christ should be to the praise of His glory.
However, Islaam says sacrifices to God can only be animals, i.e. sheep, goat, oxen, birds. This is why we don't believe Jesus Christ [FONT="]عليه[/FONT] [FONT="]السلام[/FONT] dying on a cross atones for sins.
Christs Death Fulfills Gods Will
5 Therefore, when He came into the world, He said:
Sacrifice and offering You did not desire,
But a body You have prepared for Me.
6
In burnt offerings and sacrifices for sin
You had no pleasure.
7
Then I said, Behold, I have come
In the volume of the book it is written of Me
To do Your will, O God.
8
Previously saying, Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them (which are offered according to the law), 9 then He said, Behold, I have come to do Your will, O God. He takes away the first that He may establish the second. 10 By that will we have been sanctified through the offering of the body of Jesus Christ once for all.
Christs Death Perfects the Sanctified
11 And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. 12 But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, 13 from that time waiting till His enemies are made His footstool. 14 For by one offering He has perfected forever those who are being sanctified.
15 But the Holy Spirit also witnesses to us; for after He had said before,
16
This is the covenant that I will make with them after those days, says the LORD: I will put My laws into their hearts, and in their minds I will write them, 17
then He adds, Their sins and their lawless deeds I will remember no more. 18 Now where there is remission of these,
there is no longer an offering for sin.
Hold Fast Your Confession
19 Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, 20 by a new and living way which He consecrated for us, through the veil, that is, His flesh, 21 and
having a High Priest over the house of God, 22 let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water. 23 Let us hold fast the confession of
our hope without wavering, for He who promised
is faithful. 24 And let us consider one another in order to stir up love and good works, 25 not forsaking the assembling of ourselves together, as
is the manner of some, but exhorting
one another, and so much the more as you see the Day approaching.
