Kitab al-Fitan of Nu'aym ibn Hammad: ungraded, and weak overall. Never established on its own.
يحشر الناس فلا يبقى إلا رجلان في هذا الجبل، فيقول أحدهما لصاحبه: يا فلان اذهب فانظر ما فعل الناس، فإذا حاذيا هذه الثنية، ثنية هرشى، حشرا على وجوههما
The people will be gathered, and only two men will remain on this mountain. One of them will say to his companion: O so-and-so, go and see what the people have done. When they are aligned with this fold, the bend of Harsha, they will be crowded on their faces.
