Imām Bukhārī narrates: Abū al-Yamān narrated to us, he said: Shu'aib informed us, from al-Zuhrī, he said: Anas ibn Mālik, may Allāh be pleased with him, informed me that:

when the sun had declined (from the middle of the sky), the Prophet ﷺ prayed Zuhr, then he stood upon the minbar and mentioned the Hour, then he mentioned in it great events, then he said: Whoever wishes to ask about anything, let him ask; whatever thing you ask me about, I will inform you of it, as long as I am in this place. Then most of the people began to weep, and he said repeatedly: Ask me. Then 'Abdullāh ibn Hudhāfah al-Sahmī, may Allāh be pleased with him, stood up and said: Who is my father? He said: Your father is Hudhāfah. Then he kept saying repeatedly: Ask me. Then 'Umar, may Allāh be pleased with him, sat down upon his knees, then said: We are pleased with Allāh as Lord, and with Islām as religion, and with (Sayyidunā) Muhammad ﷺ as Prophet. Then he became silent. Then he said: Just now, in the midst of this wall, Paradise and Hell were presented before me, and I have not seen the like of good and evil (before this).
