Chapter 174 | Throwing Pebbles During the Bright Days (11, 12 and 13 of Dhu al-Hajjah)
أحمد بن محمد، عن الحسين بن سعيد، عن فضالة بن أيوب، عن أبان، عن محمد الحلبي قال: سألت أبا عبدالله عليه السلام عن الغسل إذا أراد أن يرمي، فقال: ربما اغتسلت فأما من السنة فلا.
8. Ahmad ibn Muhammad has narrated from al-Husayn ibn Sa‘id from Fadalah ibn Ayyub from Aban from Muhammad al-Halabiy who has said the following: “I once asked abu ‘Abd Allah , about Ghusl (bath) when one wants to throw pebbles. He (the Imam) said, ‘Perhaps you can take Ghusl (bath) but it is not of the Sunnah.’”
