The sacrificial camels we have made for you as among the symbols from God: in them is (much) good for you: then pronounce the name of God 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. (22:36)
