5ـ مُحَمَّدُ بْنُ يَحْيَى وَغَيْرُهُ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ أَحْمَدَ بْنِ الْحَسَنِ عَنْ عَمْرِو بْنِ سَعِيدٍ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارِ بْنِ مُوسَى عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) فِي الرَّجُلِ يَجِدُ فِي رَأْسِهِ وَجَعاً مِنْ صُدَاعٍ شَدِيدٍ هَلْ يَجُوزُ لَهُ الإِفْطَارُ قَالَ إِذَا صُدِّعَ صُدَاعاً شَدِيداً وَإِذَا حُمَّ حُمَّى شَدِيدَةً وَإِذَا رَمِدَتْ عَيْنَاهُ رَمَداً شَدِيداً فَقَدْ حَلَّ لَهُ الإِفْطَارُ.

Muhammad ibn Yahya and others has narrated from Muhammad ibn Ahmad from Ahmad ibn al-Hassan from ‘Amr ibn Sa‘id from Musaddiq ibn Sadaqah from ‘Ammar ibn Musa who has said the following: “I once asked abu ‘Abd Allah , about the case of a fasting man who feels a severe headache if he can eat.
