وَ مَا رَوَاهُ سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ بْنِ أَبِي اَلْخَطَّابِ وَ عَبْدِ اَللَّهِ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَمْرِو بْنِ عُثْمَانَ عَنْ أَبِي جَمِيلَةَ اَلْمُفَضَّلِ بْنِ صَالِحٍ عَنْ سَعْدِ بْنِ طَرِيفٍ عَنِ اَلْأَصْبَغِ بْنِ نُبَاتَةَ قَالَ قَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ:« مَنْ أَدْرَكَ مِنَ اَلْغَدَاةِ رَكْعَةً قَبْلَ طُلُوعِ اَلشَّمْسِ فَقَدْ أَدْرَكَ اَلْغَدَاةَ تَامَّةً»
And what was narrated by Sa’d ibn Abdillah from Muhammad ibn al-Husayn ibn Abi al-Khattab and Abdullah ibn Muhammad ibn ‘Isa from ‘Amr ibn Uthman from Abu Jamilah al-Mufaddal ibn Salih from Sa’d ibn Tarif from al-Asbagh ibn Nubatah, who said:
Commander of the Faithful (Imam Ali ibn Abi Talib عليه السلام) said: "Whoever catches a rak’ah of the morning prayer before the rising of the sun has caught the full morning prayer."
