Friday Prayer is one of the key religious-social occasions in Islam, which can be deduced as obligatory from the Quran, tradition, and consensus. The Quran advises believers to leave their transactions and hasten towards prayer when the call to Friday Prayer is announced. This normative recommendation leads to the establishment or renewal of regulations governing various transactions and interactions in different areas. In this regard, the present study seeks to answer the question of whether the prohibition and sanctity of buying and selling extend to other contracts and transactions or are exclusive to buying and selling. Many scholars from both the Shia and Sunni schools of thought believe that sanctity is not exclusive to buying and selling but includes other contracts and anything that hinders Friday Prayer. Therefore, it seems that any other activity, including buying and selling or other transactions, contracts, or engagements that disrupt or prevent Friday Prayer, or even cause preoccupation with worldly matters and neglect of Friday Prayer as a remembrance of God, falls under the prohibition of buying and selling mentioned in the noble verse.
