1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ النَّضْرِ بْنِ سُوَيْدٍ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ أَبِي بَصِيرٍ وَمُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِنَّ الله عَزَّ وَجَلَّ فَرَضَ فِي كُلِّ سَبْعَةِ أَيَّامٍ خَمْساً وَثَلاَثِينَ صَلاَةً مِنْهَا صَلاَةٌ وَاجِبَةٌ عَلَى كُلِّ مُسْلِمٍ أَنْ يَشْهَدَهَا إِلاَّ خَمْسَةً الْمَرِيضَ وَالْمَمْلُوكَ وَالْمُسَافِرَ وَالْمَرْأَةَ وَالصَّبِيَّ.
