Nawas bin Saman reported,

The Messenger of Allah ﷺ mentioned Dajjal one morning, sometimes lowering his voice and sometimes raising it, until we thought he was hiding among the palm trees. When we went to him later, he noticed this in us and asked, "What is the matter with you?"We said, "Messenger of Allah, you mentioned Dajjal this morning, lowering and raising your voice, until we thought he was among the palm trees."He said, "It is not Dajjal that I fear most for you. If he comes out while I am among you, I will be the one to contend with him on your behalf. But if he comes out when I am no longer with you, then each man must contend with him on his own, and Allah is my deputy over every Muslim. He is a young man with very curly hair and a defective eye. I liken him to Abd al-Uzza bin Qatan. Whoever among you reaches him should recite over him the opening verses of Surah al-Kahf. He will appear on a road between Syria and Iraq, wreaking havoc to the right and to the left. Servants of Allah, hold firm."We asked, "Messenger of Allah, how long will he remain on the earth?"He said, "Forty days. One day will be like a year, one day like a month, one day like a week, and the rest of his days will be like your normal days."We asked, "Messenger of Allah, on the day that is like a year, will the prayers of one day suffice us?"He said, "No, estimate the times accordingly."We asked, "Messenger of Allah, how swiftly will he move through the earth?"He said, "Like rain driven by the wind. He will come to a people, call them, and they will believe in him and respond to him. He will then command the sky to rain and it will rain, and command the earth to bring forth produce and it will do so. Their grazing animals will return to them in the evening with their humps higher than ever, their udders fuller, and their flanks more swollen. Then he will come to another people and call them, but they will reject his words. He will turn away from them, and they will wake up in drought, with nothing of their wealth in their hands. He will pass by ruins and say to them, 'Bring out your treasures,' and the treasures will follow him like swarms of bees. Then he will summon a young man in the prime of life and strike him with a sword, cutting him into two pieces with the distance of an archer's shot between them. Then he will call him, and the youth will come forward, his face beaming and laughing.While he is doing all this, Allah will send Isa, son of Maryam, who will descend at the white minaret east of Damascus, wearing two saffron-dyed garments, with his hands placed on the wings of two angels. When he lowers his head, water will drip down, and when he raises it, droplets like pearls will roll off. No disbeliever who breathes the scent of his breath will fail to die, and his breath reaches as far as his sight reaches. He will pursue Dajjal until he catches him at the gate of Ludd and kills him.Then Isa, son of Maryam, will come to a people whom Allah has protected from Dajjal. He will wipe their faces and tell them of their ranks in Paradise. While he is doing this, Allah will reveal to Isa, 'I have brought forth servants of Mine whom no one has the power to fight. So take My servants safely to the mountain of Tur.'Allah will then send forth Yajuj and Majuj, and they will come swarming down from every height. The first of them will pass by the Lake of Tiberias and drink everything in it, and the last of them will pass by and say, 'There was once water here.'Allah's Prophet Isa and his companions will be besieged, until the head of an ox will be more valuable to one of them than a hundred Dinars are to one of you today. Allah's Prophet Isa and his companions will turn to Allah in supplication, and Allah will send a worm into the necks of Yajuj and Majuj, and they will all die together as if from a single death.Then Allah's Prophet Isa and his companions will descend to the earth, and they will not find a single hand's span of ground that is not filled with the stench of their corpses. Allah's Prophet Isa and his companions will turn to Allah in supplication, and Allah will send birds with necks like those of camels, which will carry the corpses away and cast them wherever Allah wills. Then Allah will send rain that will spare neither a house of clay nor a tent of hair, and it will wash the earth until it is left like a polished mirror.Then it will be said to the earth, 'Bring forth your fruits and restore your blessing.' On that day a group will eat from a single pomegranate and find shade beneath its rind. Milk will be so blessed that a single milch camel will be enough for a large group of people, a single milch cow will be enough for a tribe, and a single milch sheep will be enough for an entire clan.While they are in this state, Allah will send a pleasant wind that will take them under their armpits, and it will take the soul of every believer and every Muslim. Only the worst of people will remain, fornicating openly like donkeys, and upon them the Hour will come."

عن النواس بن سمعان، قال

ذكر رسول الله ﷺ الدجال ذات غداة فخفض فيه ورفع حتى ظنناه في طائفة النخل، فلما رحنا إليه عرف ذلك فينا، فقال: ما شأنكم؟ قلنا: يا رسول الله، ذكرت الدجال غداة فخفضت فيه ورفعت حتى ظنناه في طائفة النخل، فقال: غير الدجال أخوفني عليكم، إن يخرج وأنا فيكم فأنا حجيجه دونكم، وإن يخرج ولست فيكم فامرؤ حجيج نفسه، والله خليفتي على كل مسلم؛ إنه شاب قطط، عينه طافئة كأني أشبهه بعبد العزى بن قطن، فمن أدركه منكم فليقرأ عليه فواتح سورة الكهف إنه خارج خلة بين الشام والعراق فعاث يمينا وعاث شمالا، يا عباد الله فاثبتوا. قلنا: يارسول الله وما لبته في الأرض؟ قال: أربعون يوما: يوم كسنة ويوم كشهر ويوم كجمعة وسائر أيامه كأيامكم. قلنا: يا رسول الله فذلك اليوم الذي كسنة أتكفينا فيه صلاة يوم؟ قال: لا اقدروا له قدره. قلنا: يا رسول الله، وما إسراعه في الأرض؟ قال: كالغيث استدبرته الريح، فيأتي على القوم فيدعوهم فيؤمنون به، ويستجيبون له، فيأمر السماء فتمطر والأرض فتنبت، فتروح عليهم سارحتهم أطول ما كانت ذرا، وأسبغه ضروعا وأمده خواصر، ثم يأتي القوم فيدعوهم فيردون عليه قوله، فينصرف عنهم فيصبحون ممحلين ليس بأيديهم شيء من أموالهم، ويمر بالخربة فيقول لها: أخرجي كنوزك فتتبعه كنوزها كيعاسيب النحل، ثم يدعو رجلا ممتلئا شبابا فيضربه بالسيف فيقطعه جزلتين رمية الغرض. ثم يدعوه فيقبل ويتهلل وجهه، يضحك، فبينما هو كذلك إذ بعث الله المسيح ابن مريم فينزل عند المنارة البيضاء شرقي دمشق بين مهر ودتين واضعا كفيه على أجنحة ملكين إذا طأطأ رأسه قطر، وإذا رفعه تحدر منه جمان كاللؤلؤ، فلا يحل لكافر يجد ريح نفسه إلا مات، ونفسه ينتهي حيث ينتهي طرفه، فيطلبه حتى يدركه بباب لد، فيقتله. ثم يأتي عيسى ابن مريم قوم قد عصمهم الله منه فيمسح عن وجوههم ويحدثهم بدرجاتهم في الجنة، فبينما هو كذلك إذ أوحى الله إلى عيسى: إني قد أخرجت عبادا لي، لا يدان لأحد بقتالهم فحرز عبادي إلى الطور، ويبعث الله يأجوج ومأجوج وهم من كل حدب ينسلون، فيمر أوائلهم على بحيرة طبرية فيشربون ما فيها، ويمر آخرهم فيقولون: لقد كان بهذه مرة ماء. ويحصر نبي الله عيسى وأصحابه، حتى يكون رأس الثور لأحدهم خيرا من مائة دينار لأحدكم اليوم، فيرغب نبي الله عيسى وأصحابه فيرسل الله عليهم النغف في رقابهم فيصبحون فرسى كموت نفس واحدة، ثم يهبط نبي الله عيسى وأصحابه، إلى الأرض فلا يجدون في الأرض موضع شبر إلا ملأه زهمهم ونتنهم فيرغب نبي الله عيسى وأصحابه إلى الله، فيرسل الله طيرا كأعناق البحت فتحملهم حيث شاء الله، ثم يرسل الله مطرا لا يكن منه بيت مدر ولا وبر فيغسل الأرض حتى يتركها كالزلفة ثم يقال للأرض: أنبتي ثمرتك وردي بركتك، فيومئذ تأكل العصابة من الرمانة، ويستظلون بقحفها، ويبارك في الرسل حتى إن اللقحة من الإبل لتكفي الفئام من الناس، واللقحة من البقر لتكفي القبيلة من الناس، واللقحة من الغنم لتكفي الفخذ من الناس، فبينما هم كذلك إذ بعث الله ريحا طيبة فتأخذهم تحت آباطهم فتقبض روح كل مؤمن وكل مسلم، ويبقى شرار الناس يتهارجون فيها تهارج الحمر فعليهم تقوم الساعة.
