7-97 حدثنا أبي رضي الله عنه قال: حدثنا سعد بن عبد الله، عن القاسم بن محمد الاصبهاني، عن سليمان بن داود المنقري، عن حفص بن غياث النخعي، عن أبي عبد الله عليه السلام قال: من كان مسافرا فليسافر يوم السبت، فلوأن حجرا زال عن جبل في يوم السبت لرده الله إلى مكانه
7-97 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Al-Qasim ibn Muhammad al-Isfahani, on the authority of Suleiman ibn Davood al-Munqeri, on the authority of Hafs ibn Qiyath al-Nakha’ee, on the authority of Aba Abdullah as-Sadiq (MGB), “Whoever wants to go on a journey should start on Saturday since God would return any rocks that may get loose and are about to separate from the hills to their original location on Saturdays.”
