سَأَلْتُهُ[6] عَنِ الْقَلْسِ وَ هِيَ الْجُشْأَةُ[1] يَرْتَفِعُ الطَّعَامُ مِنْ جَوْفِ الرَّجُلِ مِنْ غَيْرِ أَنْ يَكُونَ تَقَيَّأَ وَ هُوَ قَائِمٌ فِي الصَّلَاةِ قَالَ لَا يَنْقُضُ ذَلِكَ وُضُوءَهُ وَ لَا يَقْطَعُ صَلَاتَهُ وَ لَا يُفَطِّرُ صِيَامَهُ.
“I once asked abu ‘Abd Allah (a.s.), 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.’”
