I heard the Prophet ﷺ say: There has been no Prophet after Noah who has not warned his people about the antichrist (Dajjal), and I warn you of him. The Messenger of Allah ﷺ described him to us, saying: Perhaps some who have seen me and heard my words will live till his time. The people asked: Messenger of Allah! what will be the condition of our hearts on that day? Like what we are today? He replied: Or better.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنَّهُ لَمْ يَكُنْ نَبِيٌّ بَعْدَ نُوحٍ إِلاَّ وَقَدْ أَنْذَرَ الدَّجَّالَ قَوْمَهُ وَإِنِّي أُنْذِرُكُمُوهُ فَوَصَفَهُ لَنَا رَسُولُ اللَّهِ ﷺ وَقَالَ لَعَلَّهُ سَيُدْرِكُهُ مَنْ قَدْ رَآنِي وَسَمِعَ كَلاَمِي قَالُوا يَا رَسُولَ اللَّهِ كَيْفَ قُلُوبُنَا يَوْمَئِذٍ أَمِثْلُهَا الْيَوْمَ قَالَ أَوْ خَيْرٌ  

The Messenger of Allah (May peace be upon him) stood among the people and praised Allah in a way which is worthy of him, and mentioned the Antichrist (Dajjal), saying : I warn you of him, and there has been no prophet who has not warned his people about him, and Noah also warned his people about him. But I tell you about him a word which no Prophet had told his people : you should know that he will be blind in one eye, and Allah is not blind is one eye.  

قَامَ النَّبِيُّ ﷺ فِي النَّاسِ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ فَذَكَرَ الدَّجَّالَ فَقَالَ إِنِّي لأُنْذِرُكُمُوهُ وَمَا مِنْ نَبِيٍّ إِلاَّ قَدْ أَنْذَرَهُ قَوْمَهُ لَقَدْ أَنْذَرَهُ نُوحٌ قَوْمَهُ وَلَكِنِّي سَأَقُولُ لَكُمْ فِيهِ قَوْلاً لَمْ يَقُلْهُ نَبِيٌّ لِقَوْمِهِ إِنَّهُ أَعْوَرُ وَإِنَّ اللَّهَ لَيْسَ بِأَعْوَرَ
