Hajj in a dream indicates payment of debt, healing for the sick, marriage for the unmarried, repentance from sins, and meeting loved ones. Whoever sees himself setting out for Hajj is striving for a matter for which he will be rewarded. Performing Tawaf (circumambulating) around the Kaaba is serving the ruler or the Imam.

Hajj indicates righteousness in religion and visiting the pious. For a merchant, it is profit; for the sick, healing; and for the indebted, payment of debt. Whoever sees that he missed the Hajj will be dismissed from his position or lose in his trade.

Hajj is interpreted as goodness, blessing, and righteousness in religious and worldly life. Whoever sees himself performing Hajj will have a long life and good deeds. Whoever sees people bidding him farewell for Hajj, it indicates his death is near.
