Musannaf Ibn Abi Shaybah 14723 — The Black Stone: where did it come

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."
