Chapter 27 | The Case of a Fasting Person’s Vomiting, Nauseating or Burping
6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنِ الْقَلْسِ وَهِيَ الْجُشْأَةُ يَرْتَفِعُ الطَّعَامُ مِنْ جَوْفِ الرَّجُلِ مِنْ غَيْرِ أَنْ يَكُونَ تَقَيَّأَ وَهُوَ قَائِمٌ فِي الصَّلاةِ قَالَ لا يَنْقُضُ ذَلِكَ وُضُوءَهُ وَلا يَقْطَعُ صَلاتَهُ وَلا يُفَطِّرُ صِيَامَهُ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah, who has said the following: “I once asked abu ‘Abd Allah , about burping which is belching and brings food up from the inside of a man without vomiting and when he is standing in Salat (prayer). He (the Imam) said, ‘It does not invalidate his wudu’, destroy his Salat (prayer) or invalidate his fast.’”
