Hazrat Anas bin Malik (may Allah be pleased with him) narrates that one day the Messenger of Allah (peace and blessings be upon him) came to us in a state of anger, and we thought that Gabriel was with him. He says, I have not seen a day with more weeping than that day. The Prophet said, "Ask me questions. By Allah, whatever you ask me, I will inform you about it." He says that a man stood up and said, "O Messenger of Allah! Will I be in Paradise or in Hell?" The Prophet replied, "No, rather in Hell." Another man stood up and said, "O Messenger of Allah! Who is my father?" The Prophet replied, "Your father is Hudhafah." Another man stood up and said, "O Messenger of Allah! Is Hajj obligatory upon us every year?" The Prophet replied, "If I say yes, it will become obligatory. If it becomes obligatory, you will not be able to perform it, and if you do not perform it, you will be punished." He says that upon this, Hazrat Umar bin Khattab stood up and said, "We are pleased with Allah as our Lord, with Islam as our religion, and with Muhammad (peace and blessings be upon him) as our Messenger. O Messenger of Allah! Our time of ignorance is near, do not expose our evils, do not disgrace us because of our hidden deeds, and forgive us. Allah has forgiven you." He says that after this, the Prophet's state ended, then he turned towards the wall and said, "I have not seen anything like today in terms of good and evil. I saw Paradise and Hell by this wall."
