The Messenger of Allah ﷺ said, "If a lead ball like this," and he pointed to something the size of a skull, "were sent down from the sky to the earth, a distance of five hundred years' travel, it would reach the earth before nightfall. But if it were sent down from the top of the chain, it would travel for forty autumns, night and day, before reaching its base or its bottom."
قال رسول الله ﷺ: لو أن رصاصة مثل هذه- وأشار إلى مثل جمجمة- أرسلت من السماء إلى الأرض وهي مسيرة خمس مائة سنة لبلغت الأرض قبل الليل، ولو أنها أرسلت من رأس السلسلة لسارت أربعين خريفا الليل والنهار قبل أن تبلغ أصلها أو قعرها.
Tirmidhi (2588), Ahmad (6856), and Hakim (2/438–439) narrated it, in abbreviated form, all through routes going back to Abdullah bin Yazid Muqri, who said, Saeed bin Yazid informed us, from Abu Samh, from Isa bin Hilal Sadafi, from Abdullah bin Amr, who said, then he mentioned it.Hakim added, "And the Messenger of Allah ﷺ recited "When the shackles are around their necks and the chains, they will be dragged (71) in boiling water" [Ghafir 40:71–72] and the following verses."Its chain is hasan because of Abu Samh, who is Darraj bin Saman, for he is hasan al-hadith apart from his narration from Abu Haytham, and this narration is from him.Tirmidhi said, "This hadith's chain is hasan," and in one copy, "hasan sahih." And Hakim said, "This hadith has a sahih chain."
