Hadith 8عَنْهُ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ: قُلْتُ أَصَابَ ثَوْبِي دَمُ رُعَافٍ أَوْ غَيْرُهُ أَوْ شَيْءٌ مِنْ مَنِيٍّ فَعَلَّمْتُ أَثَرَهُ إِلَى أَنْ أُصِيبَ لَهُ مِنَ اَلْمَاءِ فَأَصَبْتُ وَ حَضَرَتِ اَلصَّلاَةُ وَ نَسِيتُ أَنَّ بِثَوْبِي شَيْئاً وَ صَلَّيْتُ ثُمَّ إِنِّي ذَكَرْتُ بَعْدَ ذَلِكَ قَالَ «تُعِيدُ اَلصَّلاَةَ وَ تَغْسِلُهُ» قُلْتُ فَإِنِّي لَمْ أَكُنْ رَأَيْتُ مَوْضِعَهُ وَ عَلِمْتُ أَنَّهُ قَدْ أَصَابَهُ فَطَلَبْتُهُ فَلَمْ أَقْدِرْ عَلَيْهِ فَلَمَّا صَلَّيْتُ وَجَدْتُهُ قَالَ« تَغْسِلُهُ وَ تُعِيدُ» قُلْتُ فَإِنْ ظَنَنْتُ أَنَّهُ قَدْ أَصَابَهُ وَ لَمْ أَتَيَقَّنْ ذَلِكَ فَنَظَرْتُ فَلَمْ أَرَ شَيْئاً ثُمَّ صَلَّيْتُ فَرَأَيْتُ فِيهِ قَالَ« تَغْسِلُهُ وَ لاَ تُعِيدُ اَلصَّلاَةَ» قُلْتُ لِمَ ذَلِكَ قَالَ« لِأَنَّكَ كُنْتَ عَلَى يَقِينٍ مِنْ طَهَارَتِكَ ثُمَّ شَكَكْتَ فَلَيْسَ يَنْبَغِي لَكَ أَنْ تَنْقُضَ اَلْيَقِينَ بِالشَّكِّ أَبَداً» قُلْتُ فَإِنِّي قَدْ عَلِمْتُ أَنَّهُ قَدْ أَصَابَهُ وَ لَمْ أَدْرِ أَيْنَ هُوَ فَأَغْسِلَهُ قَالَ« تَغْسِلُ مِنْ ثَوْبِكَ اَلنَّاحِيَةَ اَلَّتِي تَرَى أَنَّهُ قَدْ أَصَابَهَا حَتَّى تَكُونَ عَلَى يَقِينٍ مِنْ طَهَارَتِكَ» قُلْتُ فَهَلْ عَلَيَّ إِنْ شَكَكْتُ فِي أَنَّهُ أَصَابَهُ شَيْ ءٌأَنْ أَنْظُرَ فِيهِ قَالَ« لاَ وَلَكِنَّكَ إِنَّمَا تُرِيدُ أَنْ تُذْهِبَ اَلشَّكَّ اَلَّذِي وَقَعَ فِي نَفْسِكَ» قُلْتُ إِنْ رَأَيْتُهُ فِي ثَوْبِي وَ أَنَا فِي اَلصَّلاَةِ قَالَ« تَنْقُضُ اَلصَّلاَةَ وَ تُعِيدُ إِذَا شَكَكْتَ فِي مَوْضِعٍ مِنْهُ ثُمَّ رَأَيْتَهُ وَ إِنْ لَمْ تَشُكَّ ثُمَّ رَأَيْتَهُ رَطْباً قَطَعْتَ اَلصَّلاَةَ وَغَسَلْتَهُ ثُمَّ بَنَيْتَ عَلَى اَلصَّلاَةِ لِأَنَّكَ لاَ تَدْرِي لَعَلَّهُ شَيْءٌ أُوقِعَ عَلَيْكَ فَلَيْسَ يَنْبَغِي أَنْ تَنْقُضَ اَلْيَقِينَ بِالشَّكِّ».
From him, from Hammad, from Hariz, from Zurarah, who said:
I said to Abu Abdullah (a.s): "Blood from a nosebleed, or something like it, or some semen touched my garment. I knew the spot but waited to find water. When I found water and it was time for prayer, I forgot about the impurity and prayed. Then I remembered it afterward." Imam (a.s) said: "You must repeat the prayer and wash it." I said: "What if I didn’t know the exact spot, but I knew it had touched the garment? I searched for it but couldn’t find it. After I prayed, I found it." Imam (a.s) said: "Wash it and repeat the prayer." I said: "What if I thought it might have touched my garment but was not certain, and after searching, I didn’t find anything? Then I prayed and later saw it?" Imam (a.s) said: "Wash it, but you do not need to repeat the prayer." I said: "Why is that?" Imam (a.s) said: "Because you were initially certain of your purity, and then you doubted. It is not proper to overturn certainty with doubt." I said: "What if I knew it had touched my garment but didn’t know where? Should I wash it?" Imam (a.s) said: "Wash the area of the garment where you think it touched until you are certain of its purity." I said: "If I doubt whether anything touched it, must I check it?" Imam (a.s) said: "No. But if you want to remove the doubt in your mind, you may check." I said: "If I see it on my garment during prayer?" Imam (a.s) said: "Stop the prayer and repeat it. If you doubted its presence and then saw it, or if you didn’t doubt but later found it wet, interrupt the prayer, wash it, and continue the prayer from where you left off. This is because you do not know - it could have been placed on you during the prayer. It is not proper to overturn certainty with doubt."
