Musnad Ahmad

It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Messenger of Allah (peace and blessings be upon him) came out after the decline of the sun, led the Zuhr prayer, and after saying salam, stood on the pulpit and mentioned the Day of Judgment: and also that before it, very important matters will occur. Then he said, "Whoever wants to ask any question, let him ask. By Allah! Whatever you ask me about, as long as I am standing here, I will surely answer you." Hearing this, the people began to weep and wail in abundance, and the Prophet (peace and blessings be upon him) kept repeating, "Ask me." So a man stood up and asked, "O Messenger of Allah (peace and blessings be upon him)! Where will I enter?" He replied, "In Hell." Abdullah bin Hudhafah (may Allah be pleased with him) asked, "O Messenger of Allah (peace and blessings be upon him)! Who is my father?" The Prophet (peace and blessings be upon him) said, "Your father is Hudhafah." Upon this, Hazrat Umar (may Allah be pleased with him) knelt down and began to say, "We are pleased and content with Allah as our Lord, Islam as our religion, and Muhammad (peace and blessings be upon him) as our Prophet." Hearing this from Hazrat Umar (may Allah be pleased with him), the Prophet (peace and blessings be upon him) became silent. After a little while, he said, "By Him in Whose hand is my soul, Paradise and Hell have just been presented before me in the width of this wall, while I was praying. I have never seen a day of good and evil like today."
