Sadaka ni toleo la chochote, kama vile chakula, vitu au wanyama, kwa lengo la juu, hasa la kidini, kwa mfano kumheshimu Mungu na kujiombea fadhili fulani toka kwake. Kama sadaka inaendana na uchinjaji wa binadamu au mnyama inaweza kuitwa kafara. Fungu la Kumi Malimbuko Nadhiri Davies, Nigel (1981). Human Sacrifice: In History and Today. Dorset Press.
