Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «مَنْ رَمَى اَلْجِمَارَ يُحَطُّ عَنْهُ بِكُلِّ حَصَاةٍ كَبِيرَةٌ مُوبِقَةٌ وَ إِذَا رَمَاهَا اَلْمُؤْمِنُ اِلْتَقَفَهَا اَلْمَلَكُ وَ إِذَا رَمَاهَا اَلْكَافِرُ قَالَ اَلشَّيْطَانُ بِاسْتِكَ مَا رَمَيْتَ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Whoever casts the pebbles at the Jamarat will have a major destructive sin removed for each pebble. When a believer casts it, the angel catches it. But when a disbeliever casts it, Satan says mockingly, 'You did not truly strike me.'"
