Ethnicity in the Qur'anic term is more general than its common term meaning, and Islam has also referred to a group of people who have a certain belief and thinking as "nation".On the other hand, ethnicism is a questionable concept that can be divided into two categories, reprehensible and praiseworthy, according to the goals and motivations of its tendency.
The ethnicism of the ignorant Arabs, which can be interpreted as blind nervousness, as well as the ethnicism of the Israelites, have been condemned in different ways in the Holy Quran.
However, ethnicism with the aim of strengthening the monotheistic thinking of Islam has been considered necessary, and the return to the nation and tribe has been proposed as the goal of religious missionaries. The Holy Prophet (peace and blessings of God be upon him) was also assigned to warn his family and relatives, and instead of Islamic rules and rights, attention has been paid to the family of the merciful, which is a special part of a person's ethnicity.
Therefore, the tendency towards ethnicity with the aim of helping dear Islam and also guiding them is commendable but also necessary and obligatory.
