So mention the Name of Allah over them when they are drawn up in lines (for sacrifice). Then, when they are down on their sides (after slaughter), eat thereof, and feed the poor who does not ask (men), and the beggar who asks (men). Thus have We made them subject to you that you may be grateful.

(30) One with whom was knowledge of the Scripture said: "I will bring it to you within the twinkling of an eye!" Then when he [Sulaiman (Solomon)] saw it placed before him, he said: "This is by the Grace of my Lord - to test me whether I am grateful or ungrateful! And whoever is grateful, truly, his gratitude is for (the good of) his ownself; and whoever is ungrateful, (he is ungrateful only for the loss of his ownself). Certainly my Lord is Rich (Free of all needs), Bountiful."
