البيهقي:٨٣٩٥ – أَخْبَرَنَا أَبُو بَكْرٍ مُحَمَّدُ بْنُ إِبْرَاهِيمَ الْحَافِظُ أنبأ أَبُو نَصْرٍ أَحْمَدُ بْنُ عَمْرٍو الْعِرَاقِيُّ ثنا سُفْيَانُ بْنُ مُحَمَّدٍ الْجَوْهَرِيُّ ثنا عَلِيُّ بْنُ الْحَسَنِ ثنا عَبْدُ اللهِ بْنُ الْوَلِيدِ ثنا سُفْيَانُ عَنِ الْأَسْوَدِ بْنِ قَيْسٍ عَنْ أَبِيهِ أَنَّ عُمَرَ ؓ قَالَ مَا مِنْ أَيَّامٍ أَحَبُّ إِلَيَّ أَنْ أَقْضِيَ فِيهَا شَهْرَ رَمَضَانَ مِنْ أَيَّامِ الْعَشْرِ 8395 قَالَ وَحَدَّثَنَا سُفْيَانُ حَدَّثَنَا عُثْمَانُ بْنُ مَوْهَبٍ قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ وَسَأَلَهُ رَجُلٌ فَقَالَ إِنَّ عَلَيَّ رَمَضَانَ وَأَنَا أُرِيدُ أَنْ أَتَطَوَّعَ فِي الْعَشْرِ قَالَ

لَا بَلِ ابْدَأْ بِحَقِّ اللهِ فَاقْضِهِ ثُمَّ تَطَوَّعْ بَعْدُ مَا شِئْتَ
