6ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ شَرِيفِ بْنِ سَابِقٍ عَنِ الْفَضْلِ بْنِ أَبِي قُرَّةَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) خَيْرُ وَقْتٍ دَعَوْتُمُ الله عَزَّ وَجَلَّ فِيهِ الأسْحَارُ وَتَلا هَذِهِ الآيَةَ فِي قَوْلِ يَعْقُوبَ (عَلَيهِ السَّلام) سَوْفَ أَسْتَغْفِرُ لَكُمْ رَبِّي وَقَالَ أَخَّرَهُمْ إِلَى السَّحَرِ.
6. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Sharif ibn Sabiq from al-Fadl ibn abu Qurrah from Abu ‘Abdillah who has said the following: “The Messenger of Allah has said, ‘The best time to pray to Allah, the Most Majestic, the Most Holy, is the last part of the night’ and he read this verse that quotes Ya’qub, peace be upon him, ‘I shall ask my Lord to forgive you; He is All-Forgiving and All-Merciful.’ (12:98) He said that he (Ya’qub) waited until the last part of the night (Sahar), then he prayed.’”
