Chapter 45 | Things That Invalidate Salah (Prayer) Like Laughing, Invalidating Wudu’, Making a Gesture, Forgetting and So on
5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنِ الْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما الْسَّلام) فِي الرَّجُلِ يَمَسُّ أَنْفَهُ فِي الصَّلاَةِ فَيَرَى دَماً كَيْفَ يَصْنَعُ أَ يَنْصَرِفُ فَقَالَ إِنْ كَانَ يَابِساً فَلْيَرْمِ بِهِ وَلاَ بَأْسَ.
5. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “About a man who during Salah (prayer) touches his nose and finds blood; one of the two Imam, abu Ja‘far or abu ‘Abd Allah, ‘Alayhim al-Salam, has said, ‘If it is dry he throws it away and it is not harmful.’”
