Focus on religious obligations and avoid distractions from worldly matters while performing them .

This hadith talks about the importance of Hajj, which is one of the five pillars of Islam. It explains that in the beginning when Hajj was prescribed, people used to trade during their pilgrimage. However, this practice was later prohibited by Prophet Muhammad ﷺ as it distracted them from their main purpose of performing the rituals associated with Hajj. This hadith teaches us that we should focus on our religious obligations and not be distracted by worldly matters while performing them. We should also remember that our actions have consequences and if we do something wrong or inappropriate, there will be a punishment for it.
