وَعَنْ أَسْمَاءَ بِنْتِ يَزِيدَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”يَمْكُثُ الدَّجَّالُ فِي الْأَرْضِ أَرْبَعِينَ سَنَةً السَّنَةُ كَالشَّهْرِ وَالشَّهْرُ كَالْجُمُعَةِ وَالْجُمُعَةُ كَالْيَوْمِ وَالْيَوْمُ كَاضْطِرَامِ السَّعْفَةِ فِي النَّارِ“
It is narrated from Sayyida Asma bint Yazid, may Allah be pleased with her, that the Messenger of Allah, peace and blessings be upon him, said: The Dajjal will remain on the earth for forty years; one of his years will be like a month, one month like a week, one week like a day, and one day will be like the moment in which a dry leaf burns in the fire.
