Letter 52
To the Governors of various places concerning prayers
Now, say the Zuhr prayers with the people when the shade of the wall of the goats' pen is equal to the wall. Say the Asr 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). Say the Maghrib prayers when he who is fasting ends the fast and the pilgrim rushes (from Arafat) to Mina. Say the Isha'a prayers with them when twilight disappears and up to one third of the night. Say the morning prayers with them when a man can recognize the face of his companion. Say the prayers with the people as the weakest of them would do and do not be a source of trouble to them.
