Ibn 'Abbas reported:
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، وَأَبُو بَكْرِ بْنُ خَلاَّدٍ كِلاَهُمَا عَنْ يَحْيَى الْقَطَّانِ ، - قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا يَحْيَى، - عَنْ سُفْيَانَ ، قَالَ حَدَّثَنَا حَبِيبٌ ، عَنْ طَاوُسٍ ، عَنِ ابْنِ عَبَّاسٍ ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ صَلَّى فِي كُسُوفٍ قَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ قَرَأَ ثُمَّ رَكَعَ ثُمَّ سَجَدَ . قَالَ وَالأُخْرَى مِثْلُهَا .
The Apostle of Allah (ﷺ) observed prayer while it was (solar) eclipse. He recited (the Qur'an in qiyam) and then bowed. He again recited and again bowed. He again recited and again bowed and again recited and again bowed, and then prostrated; and the second (rak'ah) was like this.
