"The sun eclipsed during the time of the Messenger of Allah ﷺ and he rushed out, dragging his cloak until he came to the masjid. He continued leading us in prayer until the eclipse ended. When it ended, he said: 'People claim that the eclipse of the sun and moon only happen when a great man dies, but that is not so. Eclipses of the sun and the moon do not happen for the death or birth of anyone, but they are signs from Allah (SWT), the Mighty and Sublime. When Allah, the Mighty and Sublime, manifests Himself to anything of His creation, it humbles itself before Him, so if you see that then pray like the last obligatory prayer you did before that.'" (Using translation from Nasāʾī 1485)  

انْكَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فَخَرَجَ يَجُرُّ ثَوْبَهُ فَزِعًا حَتَّى أَتَى الْمَسْجِدَ فَلَمْ يَزَلْ يُصَلِّي حَتَّى انْجَلَتْ فَلَمَّا انْجَلَتْ قَالَ «إِنَّ نَاسًا يَزْعُمُونَ أَنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْكَسِفَانِ إِلَّا لِمَوْتِ عَظِيمٍ مِنَ الْعُظَمَاءِ وَلَيْسَ كَذَلِكَ إِنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْكَسِفَانِ لِمَوْتِ أَحَدٍ وَلَا لِحَيَاتِهِ وَلَكِنَّهُمَا آيَتَانِ مِنْ آيَاتِ اللهِ وَإِنَّ اللهَ إِذَا تَجَلَّى لِشَيْءٍ مِنْ خَلْقِهِ خَشَعَ لَهُ فَإِذَا رَأَيْتُمْ ذَلِكَ فَصَلُّوا كَأَحْدَثِ صَلَاةٍ صَلَّيْتُمُوهَا مِنَ الْمَكْتُوبَةِ»  

"There was an eclipse of the sun and at the time we were with the Messenger of Allah ﷺ in Al-Madinah. He rushed out dragging his garment and prayed two rak'ahs, which he made lengthy. The end of his prayer coincided with the end of the eclipse. He praised and glorified Allah (SWT), then he said: 'The sun and the moon are two of the signs of Allah (SWT), and they do not become eclipsed for the death or birth of anyone. If you see anything of that, then pray like the last obligatory prayer you did before that.'" (Using translation from Nasāʾī 1486)  

كَسَفَتِ الشَّمْسُ وَنَحْنُ إِذْ ذَاكَ مَعَ رَسُولِ اللهِ ﷺ بِالْمَدِينَةِ فَخَرَجَ فَزِعًا يَجُرُّ ثَوْبَهُ فَصَلَّى رَكْعَتَيْنِ أَطَالَهُمَا فَوَافَقَ انْصِرَافُهُ انْجِلَاءَ الشَّمْسِ فَحَمِدَ اللهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ «إِنَّ الشَّمْسَ وَالْقَمَرَ آيَتَانِ مِنْ آيَاتِ اللهِ وَإِنَّهُمَا لَا يَنْكَسِفَانِ لِمَوْتِ أَحَدٍ وَلَا لِحَيَاتِهِ فَإِذَا رَأَيْتُمْ مِنْ ذَلِكَ شَيْئًا فَصَلُّوا كَأَحْدَثِ صَلَاةٍ مَكْتُوبَةٍ صَلَّيْتُمُوهَا»  

That there was an eclipse of the sun and the Prophet of Allah ﷺ prayed two rak'ahs until it ended. Then he said: "The sun and the moon do not become eclipsed for the death of anyone, but they are two of His creations. Allah, the Mighty and Sublime, causes whatever He wants to happen in His creation. If Allah (SWT), the Mighty and Sublime, manifests Himself to any of His creation, it humbles itself before Him, so if either of them (solar or lunar eclipse) happens, pray until it is over or until Allah causes something to happen." (Using translation from Nasāʾī 1487)  

أَنَّ الشَّمْسَ انْخَسَفَتْ فَصَلَّى نَبِيُّ اللهِ ﷺ رَكْعَتَيْنِ رَكْعَتَيْنِ حَتَّى انْجَلَتْ ثُمَّ قَالَ «إِنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْخَسِفَانِ لِمَوْتِ أَحَدٍ وَلَكِنَّهُمَا خَلْقَانِ مِنْ خَلْقِهِ وَإِنَّ اللهَ يُحْدِثُ فِي خَلْقِهِ مَا يَشَاءُ وَإِنَّ اللهَ إِذَا تَجَلَّى لِشَيْءٍ مِنْ خَلْقِهِ خَشَعَ لَهُ فَأَيُّهَا مَا حَدَثَ فَصَلُّوا حَتَّى يَنْجَلِيَ أَوْ يُحْدِثَ اللهُ أَمْرًا»  

The Prophet ﷺ said: "If there is an eclipse of the sun or the moon, pray like the last obligatory prayer you did before that." (Using translation from Nasāʾī 1488)  

«إِذَا انْخَسَفَتِ الشَّمْسُ وَالْقَمَرُ فَصَلُّوا كَأَحْدَثِ صَلَاةٍ صَلَّيْتُمُوهَا»  

The Messenger of Allah ﷺ prayed when there was an eclipse of the sun like our prayer, bowing and prostrating. (Using translation from Nasāʾī 1489)  

أَنَّ رَسُولَ اللهِ ﷺ «صَلَّى حِينَ انْكَسَفَتِ الشَّمْسُ مِثْلَ صَلَاتِنَا يَرْكَعُ وَيَسْجُدُ»  

The Prophet ﷺ came rushing out to the masjid one day when the sun eclipsed, and he prayed until the eclipse ended, then he said: "The people of Jahilliyyah used to say that eclipses of the sun and the moon only happened when some great man on earth died. But eclipses of the sun and the moon do not happen for the death or birth of anyone. Rather they are two of the creations of Allah (SWT) and Allah (SWT) causes to happen in His creation what He wills. Whichever of them becomes eclipsed, pray until it is over or Allah (SWT) causes something to happen." (Using translation from Nasāʾī 1490)  

عَنِ النَّبِيِّ ﷺ أَنَّهُ خَرَجَ يَوْمًا مُسْتَعْجِلًا إِلَى الْمَسْجِدِ وَقَدِ انْخَسَفَتِ الشَّمْسُ فَصَلَّى حَتَّى انْجَلَتْ ثُمَّ قَالَ إنَّ أَهْلَ الْجَاهِلِيَّةِ كَانُوا يَقُولُونَ إِنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْخَسِفَانِ إِلَّا لِمَوْتِ عَظِيمٍ مِنْ عُظَمَاءِ أَهْلِ الْأَرْضِ وَإِنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْخَسِفَانِ لِمَوْتِ أَحَدٍ وَلَا لِحَيَاتِهِ وَلَكِنَّهُمَا خَلِيقَتَانِ مِنْ خَلْقِهِ يُحْدِثُ اللهُ فِي خَلْقِهِ مَا شَاءَ وَأَيُّهُمَا انْخَسَفَ فَصَلُّوا حَتَّى يَنْجَلِيَ أَوْ يُحْدِثَ اللهُ أَمْرًا  

"We were with the Messenger of Allah ﷺ when the sun became eclipsed. The Messenger of Allah ﷺ went out dragging his garment, until he came to the masjid, and the people gathered around him. He led us in praying two rak'ahs and when (the eclipse) ended he said: 'The sun and the moon are two of the signs of Allah (SWT) by means of which Allah (SWT), the Mighty and Sublime, strikes fear into His slaves. They do not become eclipsed for the death or birth of anyone. If you see that, then pray until Allah (SWT)r relieves you of fear.' That was because his son named Ibrahim had died, and the people suggested to him that (the eclipse) happened because of that." (Using translation from Nasāʾī 1491)  

كُنَّا عِنْدَ رَسُولِ اللهِ ﷺ فَانْكَسَفَتِ الشَّمْسُ فَخَرَجَ رَسُولُ اللهِ ﷺ يَجُرُّ رِدَاءَهُ حَتَّى انْتَهَى إِلَى الْمَسْجِدِ وَثَابَ إِلَيْهِ النَّاسُ فَصَلَّى بِنَا رَكْعَتَيْنِ فَلَمَّا انْكَشَفَتْ قَالَ «إِنَّ الشَّمْسَ وَالْقَمَرَ آيَتَانِ مِنْ آيَاتِ اللهِ يُخَوِّفُ اللهُ بِهِمَا عِبَادَهُ وَإِنَّهُمَا لَا يَنْخَسِفَانِ لِمَوْتِ أَحَدٍ وَلَا لِحَيَاتِهِ فَإِذَا رَأَيْتُمْ ذَلِكَ فَصَلُّوا حَتَّى يُكْشَفَ مَا بِكُمْ» وَذَاكَ أَنَّ ابْنًا لَهُ مَاتَ يُقَالُ لَهُ إِبْرَاهِيمُ فَقَالَ نَاسٌ فِي ذَلِكَ  

The Messenger of Allah ﷺ prayed two rak'ahs like this prayer of yours, and he mentioned the eclipse of the sun. (Using translation from Nasāʾī 1492)  

أَنَّ رَسُولَ اللهِ ﷺ «صَلَّى رَكْعَتَيْنِ مِثْلَ صَلَاتِكُمْ هَذِهِ وَذَكَرَ كُسُوفَ الشَّمْسِ»
