FALSE MESSIAH H H 206 "When the Prophet, praise and peace be upon him, was with us we were discussing the meaning of "Farewell Pilgrimage", we had not understood the expression until he stood up and praised Allah, and talked at length about the anti-christ. The Prophet, praise and peace be upon him, told us: 'Every Prophet sent by Allah has warned his nation against his (the anti-christ's) mischief. Noah warned and so did all the prophets after him. If he appears among you, his appearance will not be unknown to you. It is well known to you that your Lord is not one-eyed, but the anti-christ is one-eyed. His right eye is like a floating grape. Beware, Allah has prohibited you from shedding each other's blood and the theft of one another's possessions, like the sanctity of this day and this month. Listen, have I conveyed the Message of Allah?' The Companions replied: 'Yes.' Then he supplicated: 'Bear witness, O Allah' and repeated it three times. He concluded: 'Woe to you, take heed and do not revert to disbelief after I am gone, some of you slaying others.'" R 206 Bukhari and part in Muslim with a chain up to Ibn Omar who related this.
205- وعن ابن عمر رضي الله عنهما ، قال : كُنَّا نَتَحَدَّثُ عَنْ حَجَّةِ الوَدَاعِ ، والنَّبيُّ صلى الله عليه وآله وسلم بَيْنَ أظْهُرِنَا ، وَلا نَدْرِي مَا حَجَّةُ الوَدَاعِ حَتَّى حَمِدَ اللهَ رَسُول الله صلى الله عليه وآله وسلم وَأثْنَى عَلَيهِ ثُمَّ ذَكَرَ المَسْيحَ الدَّجَّال فَأطْنَبَ في ذِكْرِهِ ، وَقَالَ : "مَا بَعَثَ اللهُ مِنْ نَبيٍّ إلاَّ أنْذَرَهُ أُمَّتَهُ أنْذَرَهُ نُوحٌ وَالنَّبِيُّونَ مِنْ بَعْدِهِ ، وَإِنَّهُ إنْ يَخْرُجْ فِيكُمْ فَما خَفِيَ عَليْكُمْ مِنْ شَأنِه فَلَيْسَ يَخْفَى عَليْكُم ، إنَّ رَبَّكُمْ لَيْسَ بأعْوَرَ وإنَّهُ أعْوَرُ عَيْنِ اليُمْنَى ، كَأنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ . ألا إنَّ الله حَرَّمَ عَلَيْكُمْ دِمَاءكُمْ وَأمْوَالَكُمْ كحُرْمَةِ يَوْمِكُمْ هَذَا ، في بلدكم هذا ، في شَهْرِكُمْ هَذَا ، ألا هَلْ بَلّغْتُ ؟" قالُوا : نَعَمْ ، قَالَ : "اللَّهُمَّ اشْهَدْ" ثلاثاً" وَيْلَكُمْ - أَوْ وَيْحَكُمْ - ، انْظُروا : لا تَرْجعُوا بَعْدِي كُفّاراً يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ" رواه البخاري ، وروى مسلم بعضه .
