Final answer:
Muslims wait for an opportunity to touch the Black Stone as part of the pilgrimage to Mecca.
Step-by-step explanation:
As part of a pilgrimage to Mecca, Muslims wait for an opportunity to touch the Black Stone. Upon arriving in Mecca, pilgrims gather in the courtyard of the Masjid al-Haram around the Kaaba. They then circumambulate or walk around the Kaaba, during which they hope to kiss and touch the Black Stone, embedded in the eastern corner of the Kaaba.
