Chapter 189 | Steadfast and transient belief, the challenge: "Ask me before you miss me"
[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.
