الحجر الأسود
The Hajar al-Aswad (হাজরে আসওয়াদ) is a sacred stone set into the eastern corner of the কাবা শরীফ in মক্কা মুকাররমা. Muslims begin and end each circuit of তাওয়াফ at this point. নবী করীম Muhammad (PBUH) placed it in its current position during the কাবা শরীফ's reconstruction.
The হাজরে আসওয়াদ is believed by Muslims to date back to the time of Prophet Adam (AS) and was originally white, turning black from absorbing the sins of humanity. When the Quraysh rebuilt the কাবা শরীফ, a dispute arose over who should place the stone. Prophet Muhammad (PBUH) resolved it by having representatives of each clan hold a cloth carrying the stone, then placing it himself. The stone has been broken into fragments over the centuries and is now held together by a silver frame.
The হাজরে আসওয়াদ marks the starting and ending point of তাওয়াফ. Kissing or pointing to it is a sunnah of নবী করীম Muhammad (PBUH). It is considered a stone from Paradise and will testify on the Day of Judgment for those who touched it with sincerity.
The হাজরে আসওয়াদ is located at the eastern corner of the কাবা শরীফ, marked by a green light. During peak times, kissing or touching the stone is extremely difficult due to crowds. It is sunnah to kiss it if possible, touch it, or simply point toward it and say 'Allahu Akbar' from a distance. Each তাওয়াফ circuit begins and ends at the হাজরে আসওয়াদ line.
