Conducting business during the Hajj season is permissible according to explicit Quranic permission. Allah says: 'There is no sin upon you for seeking bounty from your Lord (during Hajj)' (Al-Baqarah, 2:198). This verse was revealed because the early Muslims felt hesitant about trading during the sacred Hajj season, thinking it might diminish their worship. The Quran explicitly removed this concern.
Sheikh Ibn Baz stated that buying, selling, and trading during the Hajj season is permissible as long as it does not interfere with the performance of the Hajj rites. The companions of the Prophet engaged in commerce during the Hajj season, and the markets of Makkah were active during this time. Ibn Abbas reported that Dhul-Majaz and Ukaz were trade markets during Hajj in the pre-Islamic and Islamic periods.
Sheikh Al-Fawzan clarified an important distinction: a pilgrim who performs Hajj and also conducts some business on the side is not blameworthy. However, a person who makes the trip primarily for business and performs Hajj as a secondary activity is acting against the spirit of the pilgrimage. Hajj should be the primary intention, with business being incidental. The pilgrim should not let trade distract them from the rites, from making dua at Arafat, from the remembrance of Allah, or from the other sacred moments of Hajj.
