"I heard Ubaid bin Umair say: 'Someone whom I trust'- and I think he meant Aishah- told me: There was an eclipse of the sun during the time of the Messenger of Allah ﷺ. He led the people in prayer and stood for a very long time, then he bowed, then he stood, then he bowed, then he stood, then he bowed. He prayed two rak'ahs, bowing three times in each rak'ah. After bowing for the third time he prostrated for a long time. Some men fainted on that day and had to be revived by having buckets of water thrown over them, because of having stood for so log. When he bowed, he said: Allahu Akbar, and when he raised his head, he said: Sami' Allahu lima hamidah.He did not finish until the eclipse had ended. Then he stood and praised and glorified Allah (SWT) and said: The sun and moon do not eclipse for the death or birth of anyone, but they are two of the signs of Allah (SWT) with which He strikes fear unto you. If they are eclipsed then turn to the remembrance of Allah, the Mighty and Sublime, until it (the eclipse) is over.'" (Using translation from Nasāʾī 1470)
أَنَّهَا قَالَتْ كَسَفَتِ الشَّمْسُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فَقَامَ بِالنَّاسِ قِيَامًا شَدِيدًا يَقُومُ بِالنَّاسِ ثُمَّ يَرْكَعُ ثُمَّ يَقُومُ ثُمَّ يَرْكَعُ ثُمَّ يَقُومُ ثُمَّ يَرْكَعُ فَرَكَعَ رَكْعَتَيْنِ فِي كُلِّ رَكْعَةٍ ثَلَاثَ رَكَعَاتٍ رَكَعَ الثَّالِثَةَ ثُمَّ سَجَدَ حَتَّى إِنَّ رِجَالًا يَوْمَئِذٍ لَيُغْشَى عَلَيْهِمْ حَتَّى إِنَّ سِجَالَ الْمَاءِ لَتُصَبُّ عَلَيْهِمْ مِمَّا قَامَ بِهِ يَقُولُ إِذَا رَكَعَ اللهُ أَكْبَرُ وَإِذَا رَفَعَ رَأْسَهُ قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَلَمْ يَنْصَرِفْ حَتَّى تَجَلَّتِ الشَّمْسُ فَقَامَ فَحَمِدَ اللهَ وَأَثْنَى عَلَيْهِ وَقَالَ «إِنَّ الشَّمْسَ وَالْقَمَرَ لَا يَنْكَسِفَانِ لِمَوْتِ أَحَدٍ وَلَا لِحَيَاتِهِ وَلَكِنْ آيَتَانِ مِنْ آيَاتِ اللهِ يُخَوِّفُكُمْ بِهِمَا فَإِذَا كُسِفَا فَافْزَعُوا إِلَى ذِكْرِ اللهِ حَتَّى يَنْجَلِيَا»
