8. It is narrated from him (narrator of the Hadith above) from Sa’dan ibn Muslim from Ishaq ibn ‘Ammar from Abu ‘Abdillah عليه السلام who has said the following: “Whoever performs a single Tawaf (walking seven times around the Ka’ba for worship) of this House Allah, the Most Majestic, the Most Holy, writes down for him six thousand good deeds, deletes his six thousand sins, and raises him six thousand degrees in meritorious status until he reaches al-Multazam (a part of Ka’ba) Allah then opens seven doors of paradise for him.’ I then asked, ‘May Allah keep my soul in service for your cause, all these rewards just for one Tawaf (walking seven times around the Ka’ba for worship)?’ The Imam said, ‘Yes, and I can tell you something better than this and that is helping the wish of a Muslim to come true. It is better than a Tawaf, a Tawaf. . . . (walking seven times around the Ka’ba for worship), the Imam repeated ten times.’”
