Q: If a person lives in the premises of the meeqat like Jeddah then is it obligatory for them to do tawaaf of the kaaba on every visit if not in ihraam? If they go for jumua salah then they have to do tawaf or they can go only for salaah? I heard that it is the right of kaaba that if one visits it one should do tawaaf.
