Perhaps "cyclical revelation" is a more appropriate term. Likewise, the Jews had many dietary restrictions, including pork and camel meat, the Christians were loosed from dietary restrictions, and the Muslims have some dietary restrictions (no pork, but camel meat is OK.).
Huenda "mtiririko wa ufunuo" ni neno bora zaidi. Vilevile, Wayahudi walikuwa na miiko kadhaa ya vyakula ikiwa ni pamoja na nyama ya nguruwe na ngamia, Wakristo waliwekwa huru na miiko ya vyakula, na Waislam wana baadhi ya miiko ya vyakula (hakuna kula nyama ya nguruwe lakini ya ngamia ni sawasawa).
