The Sacrifice and Eid

Allah the Almighty told us of Abraham's affliction with his beloved son:

"And he said after his rescue from the fire:

'Verily! I am going to my Lord. He will guide me! My Lord! Grant me (offspring) from the

righteous." SO We gave him the glad tidings of a forbearing boy. And when he (his son) was old

enough to walk with him, he said: "O my son! I have seen in a dream that I am slaughtering you

(offer you in sacrifice to Allah), so look what do you think!Ý" "O my father! Do that which you

are commanded InshAllah (if Allah wills), you shall find me of the patient."

 Then when they had both submitted themselves to the Will of Allah and he had laid him

prostrate on his forehead (or on the side of his forehead for slaughtering); and We called out to

him: "O Abraham! You have fulfilled the dream (vision!" Verily! Thus do Wereward those who

perform good deeds, totally for Allah's sake only. Verily, that indeed was a manifest trial and We

ransomed him with a great sacrifice (a ram;) and We left for him ( a goodly remembrance)

among generations (to come) in later times. "Salamun (peace) be upon Abraham!" Thus indeed

do We reward the Muhsineen (good doers). Verily, he was one of Our believing slaves. (Ch

37:99-111 Quran)

And muslims are rewarded an EID on which they should sacrifice in the name of ALLAH remembering the sacrifice of Hazrat Ibrahim ( A.S) and Hazrat Ismail (A.S).
