46 - حَدَّثَنا أَبي رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا سَعْدُ بْنُ عَبْدِ اللَّه قالَ: حَدَّثَنا مُحَمَّدِ بْنِ الحُسَيْنِ بْنِ أَبي الخَطَّاب، عَنْ إِبْراهيمِ بْنِ أَبي مَحْمُودٍ، عَنْ أَبي الحَسَن الرِّضا عَلَيْهِ السَّلامُ قالَ: سَأَلْتُهُ عَنِ الْقَيْ‏ءِ وَالرُّعَافِ وَالْمِدَّةِ وَالدَّمِ أَيَنْقُضُ الْوُضُوءَ قَالَ لا لا يَنْقُضُ شَيْئاً.

30-46 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Al-Hussein Abil Khattab, on the authority of Ibrahim ibn Abi Mahmood that Abil Hassan Al-Ridha (s) was asked, “Do vomiting, nosebleeds, pus and blood void the ablutions?” The Imam (s) replied, “No. Neither one of these will void the ablutions.”
