وَعَن عَطاء
قَالَ: إِن مضمض ثُمَّ أَفْرَغَ مَا فِي فِيهِ مِنَ الْمَاءِ لَا يضيره أَنْ يَزْدَرِدَ رِيقَهُ وَمَا بَقِيَ فِي فِيهِ وَلَا يَمْضُغُ الْعِلْكَ فَإِنِ ازْدَرَدَ رِيقَ الْعِلْكَ لَا أَقُولُ: إِنَّهُ يُفْطِرُ وَلَكِنْ يُنْهَى عَنْهُ
Ata said, “If one rinses his mouth and ejects the water in it, swallowing his saliva and anything that remains in it does him no harm; but one should not chew gum, for although I do not say that he breaks his fast he swallows the saliva produced by the gum, he is nevertheless prohibited from doing it.”
