The Holy Black Stone (The Ark of Covenant, Hajar Aswad and Maha Shiv Ling)

Hajre Aswad

And I will show wonders in the heavens and in the earth
Joel 3:3

...Upon this Ali (ibn Abi Talib) said to Umar: "This stone (Hajar Aswad) can indeed benefit and harm."... Ali (as) said: "Allah (swt) says in Quran when he created human being from the progeny of Adam (as) and made them witness over themselves and asked them if I am not your creator? Upon this all of them confirmed it. Thus Allah wrote this confirmation. And this stone has a pair of eyes, ears and a tongue and it opened its mouth upon the order of Allah (swt) who put that confirmation in it and ordered to witness it to all those worshippers who come for Hajj.
Al Hindi, Kanz-ul-Ammal

"The Black Stone is Allah's right hand on earth with which he shakes the hands of his slaves."
Tareekh Baghdad by Al-Khatib
