Chapter on the Legal Punishment for Theft
Man Lā Yaḥḍuruh al-Faqīh|Volume 4|Book 1|Chapter 12
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: "اَلْمَصْلُوبُ يُنْزَلُ عَنِ اَلْخَشَبَةِ بَعْدَ ثَلاَثَةِ أَيَّامٍ يُغَسَّلُ وَ يُدْفَنُ وَ لاَ يَجُوزُ صَلْبُهُ أَكْثَرَ مِنْ ثَلاَثَةِ أَيَّامٍ".
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "The crucified person is to be taken down from the wooden structure after three days, washed, and buried. It is not permissible to keep him crucified for more than three days."
