Sahih al-Bukhari 4402, 4403
Narrated Ibn `Umar:
We were talking about Hajjat-ul-Wada`, while the Prophet (ﷺ) was amongst us. We did not know what 
Hajjat-ul-Wada` signified. The Prophet (ﷺ) praised Allah and then mentioned Al-Masih Ad-Dajjal and 
described him extensively, saying, "Allah did not send any prophet but that prophet warned his nation 
of Al-Masih Ad-Dajjal. Noah and the prophets following him warned (their people) of him. He will 
appear amongst you (O Muhammad's followers), and if it happens that some of his qualities may be 
hidden from you, but your Lord's State is clear to you and not hidden from you. The Prophet (ﷺ) said it 
thrice. Verily, your Lord is not blind in one eye, while he (i.e. Ad-Dajjal) is blind in the right eye 
which looks like a grape bulging out (of its cluster). No doubt,! Allah has made your blood and your 
properties sacred to one another like the sanctity of this day of yours, in this town of yours, in this 
month of yours." The Prophet (ﷺ) added: No doubt! Haven't I conveyed Allah's Message to you? " They 
replied, "Yes," The Prophet (ﷺ) said thrice, "O Allah! Be witness for it." The Prophet (ﷺ) added, "Woe to 
you!" (or said), "May Allah be merciful to you! Do not become infidels after me (i.e. my death) by 
cutting the necks (throats) of one another."
حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، قَالَ أَخْبَرَنِي ابْنُ وَهْبٍ، قَالَ حَدَّثَنِي عُمَرُ بْنُ مُحَمَّدٍ، أَنَّ أَبَاهُ، حَدَّثَهُ عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كُنَّا نَتَحَدَّثُ بِحَجَّةِ الْوَدَاعِ وَالنَّبِيُّ صلى الله عليه وسلم بَيْنَ أَظْهُرِنَا، وَلاَ نَدْرِي مَا حَجَّةُ الْوَدَاعِ، فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ ثُمَّ ذَكَرَ الْمَسِيحَ الدَّجَّالَ فَأَطْنَبَ فِي ذِكْرِهِ وَقَالَ ‏"‏ مَا بَعَثَ اللَّهُ مِنْ نَبِيٍّ إِلاَّ أَنْذَرَ أُمَّتَهُ، أَنْذَرَهُ نُوحٌ وَالنَّبِيُّونَ مِنْ بَعْدِهِ، وَإِنَّهُ يَخْرُجُ فِيكُمْ، فَمَا خَفِيَ عَلَيْكُمْ مِنْ شَأْنِهِ فَلَيْسَ يَخْفَى عَلَيْكُمْ أَنَّ رَبَّكُمْ لَيْسَ عَلَى مَا يَخْفَى عَلَيْكُمْ ثَلاَثًا، إِنَّ رَبَّكُمْ لَيْسَ بِأَعْوَرَ، وَإِنَّهُ أَعْوَرُ عَيْنِ الْيُمْنَى، كَأَنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ ‏"‏‏.‏   ‏"‏ أَلاَ إِنَّ اللَّهَ حَرَّمَ عَلَيْكُمْ دِمَاءَكُمْ وَأَمْوَالَكُمْ، كَحُرْمَةِ يَوْمِكُمْ هَذَا، فِي بَلَدِكُمْ هَذَا، فِي شَهْرِكُمْ هَذَا، أَلاَ هَلْ بَلَّغْتُ ‏"‏‏.‏ قَالُوا نَعَمْ‏.‏ قَالَ ‏"‏ اللَّهُمَّ اشْهَدْ، ثَلاَثًا، وَيْلَكُمْ، أَوْ وَيْحَكُمُ، انْظُرُوا لاَ تَرْجِعُوا بَعْدِي كُفَّارًا، يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ ‏"‏‏.‏
