Al-Hajj - 22:36

وَالْبُدْنَ جَعَلْنَاهَا لَكُم مِّن شَعَائِرِ اللَّهِ لَكُمْ فِيهَا خَيْرٌ فَاذْكُرُوا اسْمَ اللَّهِ عَلَيْهَا صَوَافَّ فَإِذَا وَجَبَتْ جُنُوبُهَا فَكُلُوا مِنْهَا وَأَطْعِمُوا الْقَانِعَ وَالْمُعْتَرَّ كَذَلِكَ سَخَّرْنَاهَا لَكُمْ لَعَلَّكُمْ تَشْكُرُونَ
[22:36]
And (as for) the camels, We have made them of the signs of the religion of Allah for you; for you therein is much good; therefore mention the name of Allah on them as they stand in a row, then when they fall down eat of them and feed the poor man who is contented and the beggar; thus have We made them subservient to you, that you may be grateful.
The sacrificial camels we have made for you as among the symbols from Allah: in them is (much) good for you: then pronounce the name of Allah over them as they line up (for sacrifice): when they are down on their sides (after slaughter), eat ye thereof, and feed such as (beg not but) live in contentment, and such as beg with due humility: thus have We made animals subject to you, that ye may be grateful.
And the camels! We have appointed them among the ceremonies of Allah. Therein ye have much good. So mention the name of Allah over them when they are drawn up in lines. Then when their flanks fall (dead), eat thereof and feed the beggar and the suppliant. Thus have We made them subject unto you, that haply ye may give thanks.
