25ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ قَالَ قُلْتُ لأَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) الرَّكْعَتَانِ اللَّتَانِ قَبْلَ الْغَدَاةِ أَيْنَ مَوْضِعُهُمَا فَقَالَ قَبْلَ طُلُوعِ الْفَجْرِ فَإِذَا طَلَعَ الْفَجْرُ فَقَدْ دَخَلَ وَقْتُ الْغَدَاةِ.
25. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from ibn ’Udhaynah from Zurarah who has said the following: “I once asked abu Ja’far عليه السلام, about the two Rak’at before the morning, ‘When is the time for them?’ He (the Imam) said, ’It is before dawn. When it is dawn, it becomes time for the morning.’”
