756 - وَ كَتَبَ صَفْوَانُ بْنُ يَحْيَى إِلَى أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ: يَسْأَلُهُ عَنِ اَلرَّجُلِ مَعَهُ ثَوْبَانِ فَأَصَابَ أَحَدَهُمَا بَوْلٌ وَ لَمْ يَدْرِ أَيُّهُمَا هُوَ وَ حَضَرَتِ اَلصَّلاَةُ وَ خَافَ فَوْتَهَا وَ لَيْسَ عِنْدَهُ مَاءٌ كَيْفَ يَصْنَعُ قَالَ «يُصَلِّي فِيهِمَا جَمِيعاً.
Hadith.756 - Safwan ibn Yahya wrote to Abu Al-Hasan, Imam Musa ibn Jafar Al-Kadhim 
asking about a man who has two garments, one of which has been contaminated with urine, but he does not know which one. When the time for prayer arrives and he fears missing it, and he has no water available, what should he do?
Imam said: "He should pray in both of them."
