مَا رَوَاهُ سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ اَلْحَسَنِ بْنِ عَلِيِّ بْنِ فَضَّالٍ عَنْ عَمْرِو بْنِ سَعِيدٍ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارِ بْنِ مُوسَى اَلسَّابَاطِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ:« فِي اَلرَّجُلِ إِذَا غَلَبَتْهُ عَيْنُهُ أَوْ عَاقَهُ أَمْرٌ أَنْ يُصَلِّيَ اَلْمَكْتُوبَةَ مِنَ اَلْفَجْرِ مَا بَيْنَ أَنْ يَطْلُعَ اَلْفَجْرُ إِلَى أَنْ تَطْلُعَ اَلشَّمْسُ وَ ذَلِكَ فِي اَلْمَكْتُوبَةِ خَاصَّةً فَإِنْ صَلَّى رَكْعَةً مِنَ اَلْغَدَاةِ ثُمَّ طَلَعَتِ اَلشَّمْسُ فَلْيُتِمَّ وَ قَدْ جَازَتْ صَلاَتُهُ»
Narrated by Sa’d ibn Abdillah from Ahmad ibn al-Hasan ibn Ali ibn Faddal from ‘Amr ibn Sa’id from Musaddiq ibn Sadaqah from ‘Ammar ibn Musa al-Sabati:
Abu Abdillah عليه السلام said: "Regarding a man who is overcome by sleep or hindered by something from performing the obligatory Fajr prayer, (he may pray it) between the rising of the dawn and the rising of the sun, and that is specific to the obligatory prayer. So if he performs one rak’ah of the morning prayer and then the sun rises, he should complete (the prayer), and his prayer is valid."
