٩ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الله بْنِ الْمُغِيرَةِ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنْ رَجُلٍ أَصَابَ ثَوْبَهُ جَنَابَةٌ أَوْ دَمٌ قَالَ إِنْ كَانَ عَلِمَ أَنَّهُ أَصَابَ ثَوْبَهُ جَنَابَةٌ قَبْلَ أَنْ يُصَلِّيَ ثُمَّ صَلَّى فِيهِ وَلَمْ يَغْسِلْهُ فَعَلَيْهِ أَنْ يُعِيدَ مَا صَلَّى وَإِنْ كَانَ لَمْ يَعْلَمْ بِهِ فَلَيْسَ عَلَيْهِ إِعَادَةٌ وَإِنْ كَانَ يَرَى أَنَّهُ أَصَابَهُ شَيْ‏ءٌ فَنَظَرَ فَلَمْ يَرَ شَيْئاً أَجْزَأَهُ أَنْ يَنْضَحَهُ بِالْمَاءِ.
9. Ali ibn Ibrahim has narrated from his father from ‘Abd Allah ibn al-Mughirah from ‘Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah , about a man who finds semen or blood in his clothes. He (the Imam) said, ‘If he learns before performing Salah (prayer) that there is semen in his clothes, then performs Salah (prayer) in it without washing; he is required to perform his Salah (prayer) again, but if he did not know, he is not required to perform his Salah (prayer) again. If he thinks that something has happened then investigates but does not see anything it is sufficient to pour water on it.’”
