Hadith 910
۞
[The knowledge of the successor (wasi), his challenge “Ask me before you miss me” and prophecy about the Umayyads :] O people! ask me before you miss me, because certainly I am acquainted with the passages of the sky more than the passages of the earth, [2] and before that mischief springs upon its feet which would trample even the nosestring and destroy the wits of the people.
[علم الوصي :] أَيُّهَا النَّاسُ، سَلُوني قَبْلَ أَنْ تَفْقِدُوني، فَلاَنَا بِطُرُقِ السَّماءِ أَعْلَمُ مِنِّي بِطُرُقِ الاْرْضِ، قَبْلَ أَنْ تَشْغَرَ بِرِجْلِهَا فِتْنَةٌ تَطَأُ فِي خِطَامِهَا وَتَذْهَبُ بِأَحْلاَمِ قَوْمِهَا.
