Chapter 52 | To various governors concerning prayers
وَصَلُّوا بِهِمُ الْعَصْرَ وَالشَّمْسُ بَيْضَاءُ حَيَّةٌ فِي عُضْوٍ مِنَ النَّهَارِ حِينَ يُسَارُ فِيهَا فَرْسَخَانِ.
Say the ‘aṣr (afternoon) prayers with them when the sun is still shining in a portion of the day enough for covering the distance of two farsakhs (about six miles).
Gradings are classical jarḥ-wa-taʿdīl, name-matched to a rijāl index (not individually re-verified).
