712 - وَ سَأَلَ عُبَيْدُ اَللَّهِ بْنُ عَلِيٍّ اَلْحَلَبِيُّ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي مَسْجِدٍ يَكُونُ فِي اَلدَّارِ فَيَبْدُو لِأَهْلِهِ أَنْ يَتَوَسَّعُوا بِطَائِفَةٍ مِنْهُ أَوْ يُحَوِّلُوهُ عَنْ مَكَانِهِ فَقَالَ «لاَ بَأْسَ بِذَلِكَ» قَالَ فَقُلْتُ فَيَصْلُحُ اَلْمَكَانُ اَلَّذِي كَانَ حَشّاً زَمَاناً أَنْ يُنَظَّفَ وَ يُتَّخَذَ مَسْجِداً، قَالَ «نَعَمْ إِذَا أُلْقِيَ عَلَيْهِ مِنَ اَلتُّرَابِ مَا يُوَارِيهِ فَإِنَّ ذَلِكَ يُنَظِّفُهُ وَ يُطَهِّرُهُ.
Hadith.712 - Ubaidullah ibn Ali Al-Halabi asked Imam Jafar ibn Muhammad Al-Sadiq 
about a mosque within a house, where the owners might wish to expand part of it or move it from its original location.
Imam said: "There is no harm in that."
Ubaydullah then asked: "Would it be suitable for a place that was previously used as a latrine for a period of time to be cleaned and made into a mosque?"
Imam said: "Yes, if soil is placed over it to cover it, as this cleanses and purifies it."
