5ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سُئِلَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلاَم) عَنِ الْقَلْسِ يُفَطِّرُ الصَّائِمَ قَالَ لا.
5. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn, from Ali ibn al-Hakam from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “Abu Ja’far , was asked about burping if it invalidates the fast. He (the Imam) said, ‘No, it does not invalidate one’s fast.’”
