And as for the sacrifice of cattle, We have ordained it for you as one of the symbols set up by God,* in which there is [much] good for you. Hence, extol the name of God over them when they are lined up [for sacrifice]; and after they have fallen lifeless to the ground, eat of their flesh,* and feed the poor who is contented with his lot (and does not beg), as well as him who is forced to beg. It is to this end* that We have made them* subservient to your needs, so that you might have cause to be grateful.
[It was not for your enemies sake that He stayed your hands from them: for]* it was they who were bent on denying the truth, and who debarred you from the Inviolable House of Worship* and prevented your offering from reaching its destination.* And had it not been for the believing men and believing women [in Mecca ], whom you might have unwittingly trampled underfoot,* and on whose account you might have become guilty, without knowing it, of a grievous wrong-: [had it not been for this, you would have been allowed to fight your way into the city: but you were forbidden to fight]* so that [in time] God might admit to His grace whomever He wills.* Had they [who deserve Our mercy and they whom We have condemned] been clearly discernible [to you],* We would indeed have imposed grievous suffering [at your hands] on such of them as were bent on denying the truth.
