Sunan Abi Dawud 1179
Narrated Jabir:
There was an eclipse of the sun in the time of the Messenger of Allah (ﷺ) on a hot day.  The Messenger of Allah (ﷺ)led his Companions in prayer and prolonged the standing until the people began to fall down.  He then bowed and prolonged it; then he raised his head and prolonged (the stay); then he bowed and prolonged it; then he raised his head and prolonged (the stay); then he made two prostrations and then stood up; then he did in the same manner.  He thus performed four bowings and four prostrations.  Then the narrator narrated the rest of the tradition.
حَدَّثَنَا مُؤَمَّلُ بْنُ هِشَامٍ، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ هِشَامٍ، حَدَّثَنَا أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ كُسِفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي يَوْمٍ شَدِيدِ الْحَرِّ فَصَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم بِأَصْحَابِهِ فَأَطَالَ الْقِيَامَ حَتَّى جَعَلُوا يَخِرُّونَ ثُمَّ رَكَعَ فَأَطَالَ ثُمَّ رَفَعَ فَأَطَالَ ثُمَّ رَكَعَ فَأَطَالَ ثُمَّ رَفَعَ فَأَطَالَ ثُمَّ سَجَدَ سَجْدَتَيْنِ ثُمَّ قَامَ فَصَنَعَ نَحْوًا مِنْ ذَلِكَ فَكَانَ أَرْبَعَ رَكَعَاتٍ وَأَرْبَعَ سَجَدَاتٍ ‏.‏ وَسَاقَ الْحَدِيثَ ‏.‏
