In a dream it signifies the pilgrimage [Hajj].
Whoever sees that he is cutting the Black Stone wants to unite the people on his own opinion.
If he sees that the people lost the Black Stone and were searching for it, and he found it in its place, he is a man who thinks all people are in error while he is rightly guided. It may signify knowledge he alone possesses and conceals from those who seek it.
Whoever sees that he touched the Black Stone will follow an imam from the Hijaz.
If he sees that he pulled it out and took it for himself alone, he will adopt a heretical innovation in his religion apart from the Muslims.
If he sees that he swallowed it, he will lead people astray in their religion.
If he sees that he shook hands with the Black Stone, he will perform the pilgrimage. Touching [the Stone] was mentioned earlier in the chapter of Alif.
