وَ عَنْهُ عَنْ عَلِيِّ بْنِ سَيْفٍ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ قَالَ: صَحِبْتُ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ فِي اَلسَّفَرِ فَرَأَيْتُهُ يُصَلِّي اَلْمَغْرِبَ إِذَا أَقْبَلَتِ اَلْفَحْمَةُ مِنَ اَلْمَشْرِقِ يَعْنِي اَلسَّوَادَ
And from him, from Ali ibn Sayf, from Muhammad ibn Ali, who said:
I (narrator) accompanied (Imam) al-Ridha عليه السلام, during travel, and I saw Him عليه السلام pray Maghrib when the darkness appeared from the east, meaning the blackness (of night).
