The হাজরে আসওয়াদ (Hajar al-Aswad) is set in the eastern corner of the কাবা শরীফ and marks the starting point of তাওয়াফ. Islamic tradition holds it was sent down from Paradise. নবী করীম Muhammad (সাল্লাল্লাহু আলাইহি ওয়া সাল্লাম) kissed it during his তাওয়াফ. When kissing is not possible due to crowds, হাজীগণ point toward it and say 'Allahu Akbar.'
Islamic tradition holds that the হাজরে আসওয়াদ was sent down from Paradise. According to a hadith narrated by Ibn Abbas, নবী করীম Muhammad (সাল্লাল্লাহু আলাইহি ওয়া সাল্লাম) said, 'The হাজরে আসওয়াদ descended from Paradise whiter than milk, but the sins of the sons of Adam turned it black' (Tirmidhi). The stone was placed in its current position by Prophet Ibrahim when he built the কাবা শরীফ with his son Ismail. When the Quraysh rebuilt the কাবা শরীফ in 605 CE, a dispute arose over which clan would have the honor of placing the stone in the new wall. The young Muhammad resolved the conflict by placing the stone on a cloth that representatives of each clan lifted together, then setting it in place with his own hands — an event that predated his prophethood.
The হাজরে আসওয়াদ is not a single piece but consists of several fragments bound together by a silver frame. The visible surface is approximately 30 centimeters in diameter. Its fractured state is attributed to various historical incidents: it was reportedly broken during the Quraysh rebuilding, cracked by a stone catapult during the siege of মক্কা মুকাররমা by the Umayyads in 683 CE, and was stolen by the Qarmatians in 930 CE, who took it to their capital in Bahrain for 22 years before returning it. Each of these events contributed to the fragmentation of the original stone. Modern geological analysis suggests the stone may be of meteoritic origin, though this remains debated.
The হাজরে আসওয়াদ marks the starting and ending point of each circuit of তাওয়াফ. The sunnah is to kiss the stone at the beginning of each circuit, following the practice of নবী করীম Muhammad (সাল্লাল্লাহু আলাইহি ওয়া সাল্লাম). Umar ibn al-Khattab famously said, 'I know that you are a stone and can neither benefit nor harm. Had I not seen নবী করীম kiss you, I would not have kissed you' (Bukhari). When kissing is impossible due to crowd density — which is the reality for most হাজীগণ most of the time — the alternative is to touch it with the hand and then kiss the hand, or to simply face it, raise the right hand toward it, and say 'Allahu Akbar.' Causing harm to others while trying to reach the stone is explicitly condemned by scholars.
The হাজরে আসওয়াদ serves as a witness to the covenant between Allah and humanity. According to some scholarly interpretations, it represents the primordial covenant (mithaq) mentioned in আল-কুরআন (7:172) when Allah asked all souls, 'Am I not your Lord?' and they responded, 'Yes, we bear witness.' নবী করীম said that the stone will come on the Day of Judgment with two eyes and a tongue, testifying on behalf of those who touched it with sincerity (Tirmidhi, Ibn Majah). While Muslims do not worship the stone — as Umar's statement makes clear — they honor it as a sign and a connection to the prophetic tradition of Ibrahim and Muhammad (peace be upon them both).
