736 - وَ سَأَلَ عَلِيُّ بْنُ جَعْفَرٍ أَخَاهُ مُوسَى بْنَ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ: عَنِ اَلْبَيْتِ وَ اَلدَّارِ لاَ تُصِيبُهُمَا اَلشَّمْسُ وَ يُصِيبُهُمَا اَلْبَوْلُ وَ يُغْتَسَلُ فِيهِمَا مِنَ اَلْجَنَابَةِ أَ يُصَلَّى فِيهِمَا إِذَا جَفَّا قَالَ «نَعَمْ» قَالَ وَ سَأَلْتُهُ عَنِ اَلصَّلاَةِ بَيْنَ اَلْقُبُورِ هَلْ تَصْلُحُ فَقَالَ «لاَ بَأْسَ بِهِ.
Hadith.736 - Ali ibn Ja'far asked his brother Imam Musa ibn Jafar Al-Kadhim 
about a house or room that does not receive sunlight and in which urine might be present and where one bathes after major ritual impurity (janabah).
He asked if it is permissible to pray there once it has dried?
Imam said: "Yes."
Ali ibn Ja'far also asked about praying between graves?
Imam said: "There is no harm in it."
