Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 36
رَوَى مُنْذِرُ بْنُ جَيْفَرٍ عَنْ يَحْيَى بْنِ طَلْحَةَ اَلنَّهْدِيِّ قَالَ قَالَ لَنَا أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: «سِيرُوا وَ اِنْسَلُّوا فَإِنَّهُ أَخَفُّ عَلَيْكُمْ ».
Munthir ibn Ja‘far narrated from Yahya ibn Talhah al-Nahdi, who said that Imam Abu Abdullah عليه السلام said to us: "Travel in small groups and slip away quietly; it will be easier for you."
