It is narrated from Mujahid that he said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) asked me: "Do you know how vast Hell is?" I said: "No." He said: "Yes, by Allah, you do not know. Indeed, between the earlobe of one of them (the people of Hell) and his shoulder is a distance of seventy years' travel, in which there are valleys of pus and blood." I asked: "Are they rivers?" He said: "No, rather they are valleys." Then he asked: "Do you know how vast Hell is?" I said: "No." He said: "Yes, by Allah, you do not know. Sayyidah Aishah (may Allah be pleased with her) told me that she asked the Messenger of Allah (peace and blessings be upon him) about this saying of Allah, the Mighty and Majestic: "And the whole earth will be in His grip on the Day of Resurrection, and the heavens will be folded in His right hand" [Surah al-Zumar: 67] . I said: 'O Messenger of Allah, where will the people be on that day?' He (peace and blessings be upon him) said: 'On the bridge (Sirat) over Hell.'" This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) but the two Shaykhs (Bukhari and Muslim) did not record it with this wording.
