"The sun eclipsed during the time of the Messenger of Allah ﷺ on a very hot day. The Messenger of Allah ﷺ led his companions in prayer, and he stood for so long that they started to fall over. Then he bowed for a long time, then he stood up (and remained standing) for a long time. Then he bowed again for a long time, then he stood up (again) and (remained standing) for a long time. Then he prostrated twice, then he stood up and did the same again. He started to move forward, then he started to step back. He bowed four times and prostrated four times. They used to say that eclipses of the sun and moon only happened when one of their great men died, but they are two of the signs of Allah (SWT) that He shows to you, so when an eclipse happens, pray until it is over."  

كَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فِي يَوْمٍ شَدِيدِ الْحَرِّ فَصَلَّى رَسُولُ اللَّهِ ﷺ 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 وَجَعَلَ يَتَقَدَّمُ ثُمَّ جَعَلَ يَتَأَخَّرُ فَكَانَتْ أَرْبَعَ رَكَعَاتٍ وَأَرْبَعَ سَجَدَاتٍ كَانُوا يَقُولُونَ إِنَّ الشَّمْسَ وَالْقَمَرَ لاَ يَخْسِفَانِ إِلاَّ لِمَوْتِ عَظِيمٍ مِنْ عُظَمَائِهِمْ وَإِنَّهُمَا آيَتَانِ مِنْ آيَاتِ اللَّهِ يُرِيكُمُوهُمَا فَإِذَا انْخَسَفَتْ فَصَلُّوا حَتَّى تَنْجَلِيَ  

There was an eclipse of the sun in the time of the Messenger of Allah ﷺ on a hot day. The Messenger of Allah ﷺled 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. (Using translation from Abū Dāʾūd 1179)  

خَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فِي يَوْمٍ شَدِيدِ الْحَرِّ فَصَلَّى بِأَصْحَابِهِ فَأَطَالَ الْقَيَّامَ حَتَّى جَعَلُوا يَخِرُّونَ ثُمَّ رَكَعَ فَأَطَالَ ثُمَّ رَفَعَ فَأَطَالَ ثُمَّ رَكَعَ فَأَطَالَ ثُمَّ رَفَعَ فَأَطَالَ ثُمَّ سَجَدَ سَجْدَتَيْنِ ثُمَّ قَامَ فَصَنَعَ نَحْوًا مِنْ ذَلِكَ فَكَانَتْ أَرْبَعَ رَكَعَاتٍ وَأَرْبَعَ سَجَدَاتٍ
