Semantics is the scientific study of meaning that is one of the sub-branches of linguistics and includes cognitive, historical, descriptive and etc. approaches. The descriptive approach of this science, which we mean, includes companionship and substitution. Our focus in the present research is on the companionship part of this science, and we try to deal with the relationship between the word Zakat and its derivatives with its companions through the companionship relationship. In this regard, let us understand the issue of Zakat, which is one of the branches of religion, due to the great emphasis of God among all His other commands. What adds to the importance of this research is that the word Zakat with its derivatives is mentioned 59 times in the Holy Qur'an, and certainly in a book like the Qur'an, where everything is stated in its place, the repetition of this word is not without reason. The findings of the study indicate that the word Zakat is associated with words such as Salah, Wali, Obedience to God and Obedience to the Messenger, Tab, Amen, Don al-Khuf and Al-Hazn, Barr, Muttaqoon, Jahed and Hanan and its derivatives with permission, Az Al-Basr and Hafiz Al-Faraj. In the meantime, the word "Salah" has the highest frequency of associating with Zakat, and the reason for this is that God intends to convey to Muslims the status and value of these two branches of religion, as if he considers the condition for accepting the rest of the actions of Muslims after these two acts. Those obedient to God and obedient to the Messenger and the patient and the faithful with the word Zakat are the most frequent companions.
