Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَ كَتَبَ اَلْحُسَيْنُ بْنُ سَعِيدٍ إِلَى أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ يَسْأَلُهُ: عَنْ سَرِيرِ اَلْمَيِّتِ يُحْمَلُ أَ لَهُ جَانِبٌ يُبْدَأُ بِهِ فِي اَلْحَمْلِ مِنْ جَوَانِبِهِ اَلْأَرْبَعَةِ أَوْ مَا خَفَّ عَلَى اَلرَّجُلِ يَحْمِلُ مِنْ أَيِّ اَلْجَوَانِبِ شَاءَ فَكَتَبَ عَلَيْهِ اَلسَّلاَمُ «مِنْ أَيِّهَا شَاءَ.
Hussein ibn Saeed wrote to Abu Al-Hasan Imam Ali ibn Musa Ar-Ridha عليه السلام, asking about the bier of the deceased: Is there a specific side that should be carried first from among its four sides, or can one carry it from any side that is easiest? Imam عليه السلام replied: "From whichever side he wishes."
