Clash or dialogue of civilizations is one of the issues that has been taken into consideration since the emergence of civilizations and various theories are developed as to it. Following these debates, in this field various books and papers have been authored but in these essays, the doctrines of Prophet’s Household concerning the clash or dialogue of civilizations and specifically its etiquettes have not been discussed so much. A short review of the doctrines of the Prophet’s Household leads us to the idea that firstly, dialogue is prior to the clash of civilizations; secondly, dialogue has its etiquettes that should be observed when one encounters the counterpart. Good debate, mutual respect, reliance on commonalities and ignorance of differences are part of the doctrines of the Prophet’s Household. Dialogue of civilizations can serve as a vehicle for prevention from futile war and clash and the fall of Islamic civilization and its absorption in other cultures. This issue is of double importance specifically in the present age and the best method and solution for tackling the existing baseless clashes and possible conflicts between the religions and cultures.
