6ـ مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ أَبِي الْحَسَنِ (عَلَيْهِ الْسَّلام) قَالَ سَأَلْتُهُ عَنِ الْمَيِّتِ هَلْ يُغَسَّلُ فِي الْفَضَاءِ قَالَ لاَ بَأْسَ وَإِنْ سُتِرَ بِسِتْرٍ فَهُوَ أَحَبُّ إِلَيَّ.
6. Muhammad ibn Yahya has narrated from al-‘Amrakiy from Ali ibn Ali ibn Ja‘far from his brother, abu al-Hassan (a.s.), who has said the following: “I once asked abu al-Hassan (a.s.), Is it permissible to give Ghusl (bath) to a dead body in the open? He (the Imam) said, ‘It is not harmful, but I prefer that it is covered with a covering.’”
