35ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ قَالَ قَرَأْتُ فِي كِتَابِ رَجُلٍ إِلَى أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) الرَّكْعَتَانِ اللَّتَانِ قَبْلَ صَلاَةِ الْفَجْرِ مِنْ صَلاَةِ اللَّيْلِ هِيَ أَمْ مِنْ صَلاَةِ النَّهَارِ وَفِي أَيِّ وَقْتٍ أُصَلِّيهَا فَكَتَبَ بِخَطِّهِ احْشُهَا فِي صَلاَةِ اللَّيْلِ حَشْواً.
35. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ali ibn Mahziyar from who has said the following: “I have read in a letter of a man to abu ‘Abd Allah عليه السلام, and it says, ‘Are the two Rak‘at before Salah (prayer) of dawn of Salah (prayer) during the night? Or it is of Salah (prayer) during the day and when should I perform them?’ With his handwriting he (the Imam) had written, ‘Fill them in Salah (prayer) of night a complete filling.’” (Hadith 35 and the following chapter are best explained by fatwa.)
