أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، عَنْ يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنَا حَبِيبُ بْنُ أَبِي ثَابِتٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ صَلَّى فِي كُسُوفٍ فَقَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ سَجَدَ وَالأُخْرَى مِثْلُهَا .
