The Black Stone: where did it come from?

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that Ibrahim said to his son: "Find a stone for me." He went off, and when he came back, (he saw that) Ibrahim had already set a stone in place. Isma'il said: "(Father,) where did this come from?" He said: "It was brought to me by one who did not rely on your building; Jibril brought this stone to me from the heaven."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: It (the Black Stone) is one of the stones of Paradise. Had the impure people of the Jahiliyyah not touched it, no afflicted person would touch it without being cured.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: Allah Almighty sent this stone down from Paradise; it was whiter than snow, and it was the sins of the children of Adam that turned it black.

Ka'b was asked about the Black Stone. He said: It is one of the stones of Paradise.

Sayyiduna Anas (may Allah be pleased with him) said: It is one of the stones of Paradise.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: Perform Hajj to the House of Allah and touch the Black Stone, for by Allah, it will surely be lifted away or some matter from the heaven will befall it. Two stones were sent down from Paradise; one has already been lifted away and the other will soon be lifted too. If what I say does not happen, then let whoever passes by my grave say: "This is the grave of Abdullah bin Amr, who was (Allah forbid) a liar."

It is narrated from Ziyad, the freed slave of Banu Makhzum: Had the sins of the children of Adam (the sinners) not touched this stone, no afflicted person would touch it without being cured.
