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»
