The Wahhabis have excommunicated most of the Muslims, have considered them as polytheists and even have issued permit to kill them. One of the principles of their opinion is misunderstanding of the phrase min dun illah / those other than Allah, in the Quranic verses. For Wahhabis, this concept is contrary to monotheism of lordship and prudence and it is an example of polytheism of lordship. These are verses that do not consider vilayat of those other than Allah permissible or reject the mediation of this verse and consider the worship of those other than Allah as polytheism. Wahhabis think that dun illah means ghair ullah; therefore, for them, the Muslims, especially the Shiites who believe in vilayat and intersession of the saints of God are against the clear text of the Quran and judged them as infidels and polytheists. In accordance with the verses of the Holy Quran and commentary norms, the paper investigates the precise meaning of dun illah and prove that this part always does not mean ghair ullah but in case being along with evidences it can have the meaning of ghair ullah or min qibali ghair ullah versus min qibal illah . Also, about worshiping dun illah, the same discussion will be proposed.
