No, the Hajr-e-Aswad, also known as the Black Stone, is not explicitly mentioned in the Quran.
The Quran primarily focuses on spiritual and moral guidance, focusing on the core principles of Islam. It does not delve into specific details of rituals or locations, including the Hajr-e-Aswad.
However, the Quran does mention the importance of performing the Hajj pilgrimage, which includes circumambulating the Kaaba. The Kaaba is the structure that houses the Hajr-e-Aswad.
For example, in Surah Al-Hajj, verse 29, the Quran states:
"And [it is ordained] for mankind to perform the pilgrimage to the House - for whoever is able to journey to it."
Therefore, while the Quran doesn't specifically name the Hajr-e-Aswad, it references the Hajj pilgrimage and the Kaaba, which is where the Black Stone is located.
