2ـ وَبِهَذَا الإِسْنَادِ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ فَضَالَةَ بْنِ أَيُّوبَ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الرَّجُلِ يُصَلِّي وَفِي ثَوْبِهِ عَذِرَةٌ مِنْ إِنْسَانٍ أَوْ سِنَّوْرٍ أَوْ كَلْبٍ أَ يُعِيدُ صَلاَتَهُ فَقَالَ إِنْ كَانَ لَمْ يَعْلَمْ فَلاَ يُعِيدُ.
2. Through the same chain of narrators as that of the previous Hadith it is narrated from Ali ibn Mahziyar from Fadalah ibn Ayyub from ‘Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah 
, about a man who performs Salah (prayer) and there is feces of human being, cat or dog in his clothes, ‘Must he perform his Salah (prayer) again?’ He (the Imam) said, ‘He is not required to perform his Salah (prayer) again, if he did not know about it.’”
