Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 28
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «إِنَّ اَلْأَرْوَاحَ فِي صِفَةِ اَلْأَجْسَادِ فِي شَجَرَةٍ مِنَ اَلْجَنَّةِ تَتَسَاءَلُ وَ تَتَعَارَفُ فَإِذَا قَدِمَتِ اَلرُّوحُ عَلَى اَلْأَرْوَاحِ تَقُولُ دَعُوهَا فَقَدْ أَفْلَتَتْ مِنْ هَوْلٍ عَظِيمٍ ثُمَّ يَسْأَلُونَهَا مَا فَعَلَ فُلاَنٌ وَ مَا فَعَلَ فُلاَنٌ فَإِنْ قَالَتْ لَهُمْ تَرَكْتُهُ حَيّاً اِرْتَجَوْهُ وَ إِنْ قَالَتْ لَهُمْ قَدْ هَلَكَ قَالُوا هَوَى هَوَى.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "The souls are in the form of bodies in a tree of Paradise; they converse and recognize one another. When a soul joins them, they say, 'Leave it, for it has escaped a great terror.' Then they ask it, 'What did such-and-such person do, and what did such-and-such person do?' If it responds, 'I left them alive,' they have hope for them. But if it responds, 'They have died,' they say, 'They have fallen.'".
