He attended a Khutbah one day that was delivered by Samurah bin Jundub. In his Khutbah he mentioned a hadith from the Messenger of Allah ﷺ. Samurah bin Jundub said: "One day a boy from among the Ansar and I were shooting at two targets of ours, during the time of the Messenger of Allah ﷺ, when the sun was at a height of two or three spears as it appears to one who is looking at the horizon. The sun turned black, and we said to one another, let us go to the masjid, for by Allah (SWT) this must herald some event concerning the Messenger of Allah ﷺ and his ummah. We went to the masjid and we saw the Messenger of Allah ﷺ coming out to the people. He went forward and prayed. He stood for the longest time that he had ever stood in any prayer in which he led us, but we did not hear him saying anything. Then he bowed for the longest time that he had ever bowed in any prayer in which he led us, but we did not hear him saying anything. Then he prostrated for the longest time that he had ever prostrated in any prayer in which he led us, but we did not hear him saying anything. The he did likewise in the second rak'ah. And the eclipse ended as he was sitting at the end of the second rak'ah. The he said the salam, then he praised and glorified Allah (SWT), and bore witness that there is none worthy of worship but Allah (SWT) and he bore witness that he was the slave and Messenger of Allah."

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ سَمُرَةُ بْنُ جُنْدُبٍ بَيْنَا أَنَا يَوْمًا وَغُلاَمٌ مِنَ الأَنْصَارِ نَرْمِي غَرَضَيْنِ لَنَا عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ حَتَّى إِذَا كَانَتِ الشَّمْسُ قِيدَ رُمْحَيْنِ أَوْ ثَلاَثَةٍ فِي عَيْنِ النَّاظِرِ مِنَ الأُفُقِ اسْوَدَّتْ فَقَالَ أَحَدُنَا لِصَاحِبِهِ انْطَلِقْ بِنَا إِلَى الْمَسْجِدِ فَوَاللَّهِ لَيُحْدِثَنَّ شَأْنُ هَذِهِ الشَّمْسِ لِرَسُولِ اللَّهِ ﷺ فِي أُمَّتِهِ حَدَثًا قَالَ فَدَفَعْنَا إِلَى الْمَسْجِدِ قَالَ فَوَافَيْنَا رَسُولَ اللَّهِ ﷺ حِينَ خَرَجَ إِلَى النَّاسِ قَالَ فَاسْتَقْدَمَ فَصَلَّى فَقَامَ كَأَطْوَلِ قِيَامٍ قَامَ بِنَا فِي صَلاَةٍ قَطُّ مَا نَسْمَعُ لَهُ صَوْتًا ثُمَّ رَكَعَ بِنَا كَأَطْوَلِ رُكُوعٍ مَا رَكَعَ بِنَا فِي صَلاَةٍ قَطُّ مَا نَسْمَعُ لَهُ صَوْتًا ثُمَّ سَجَدَ بِنَا كَأَطْوَلِ سُجُودٍ مَا سَجَدَ بِنَا فِي صَلاَةٍ قَطُّ لاَ نَسْمَعُ لَهُ صَوْتًا ثُمَّ فَعَلَ ذَلِكَ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ قَالَ فَوَافَقَ تَجَلِّي الشَّمْسِ جُلُوسَهُ فِي الرَّكْعَةِ الثَّانِيَةِ فَسَلَّمَ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ وَشَهِدَ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَشَهِدَ أَنَّهُ عَبْدُ اللَّهِ وَرَسُولُهُ مُخْتَصَرٌ  

When, a boy from the Ansar and I were shooting (arrows) towards two of our targets, the sun was sighted by the people at the height of two or three lances above the horizon. It became black like the black herb called tannumah. One of us said to his companion: Let us go to the mosque; by Allah, this incident of the sun will surely bring something new in the community of the Messenger of Allah ﷺ. As we reached it, we suddenly saw that he (the Prophet) had already come out (of his house). He stepped forward for a long time as much as he could do so in the prayer. But we did not hear his voice. He then performed a bowing and prolonged it as much as he could do in the prayer. But we did not hear his voice. He then prostrated himself with us and prolonged it which he never did in the prayer before. But we did not hear his voice. He then did similarly in the second rak'ah. The sun became bright when he sat after the second rak'ah. Then he uttered the salutation. He then stood up, praised Allah, and extolled Him, and testified that there was no god but Allah and testified that he was His servant and apostle. Ahmad ibn Yunus then narrated the address of the Prophet ﷺ.  

سَمُرَةُ بَيْنَمَا أَنَا وَغُلاَمٌ مِنَ الأَنْصَارِ نَرْمِي غَرَضَيْنِ لَنَا حَتَّى إِذَا كَانَتِ الشَّمْسُ قِيدَ رُمْحَيْنِ أَوْ ثَلاَثَةٍ فِي عَيْنِ النَّاظِرِ مِنَ الأُفُقِ اسْوَدَّتْ حَتَّى آضَتْ كَأَنَّهَا تَنُّومَةٌ فَقَالَ أَحَدُنَا لِصَاحِبِهِ انْطَلِقْ بِنَا إِلَى الْمَسْجِدِ فَوَاللَّهِ لَيُحْدِثَنَّ شَأْنُ هَذِهِ الشَّمْسِ لِرَسُولِ اللَّهِ ﷺ فِي أُمَّتِهِ حَدَثًا قَالَ فَدَفَعْنَا فَإِذَا هُوَ بَارِزٌ فَاسْتَقْدَمَ فَصَلَّى فَقَامَ بِنَا كَأَطْوَلِ مَا قَامَ بِنَا فِي صَلاَةٍ قَطُّ لاَ نَسْمَعُ لَهُ صَوْتًا قَالَ ثُمَّ رَكَعَ بِنَا كَأَطْوَلِ مَا رَكَعَ بِنَا فِي صَلاَةٍ قَطُّ لاَ نَسْمَعُ لَهُ صَوْتًا ثُمَّ سَجَدَ بِنَا كَأَطْوَلِ مَا سَجَدَ بِنَا فِي صَلاَةٍ قَطُّ لاَ نَسْمَعُ لَهُ صَوْتًا ثُمَّ فَعَلَ فِي الرَّكْعَةِ الأُخْرَى مِثْلَ ذَلِكَ قَالَ فَوَافَقَ تَجَلِّي الشَّمْسِ جُلُوسَهُ فِي الرَّكْعَةِ الثَّانِيَةِ قَالَ ثُمَّ سَلَّمَ ثُمَّ قَامَ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ وَشَهِدَ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَشَهِدَ أَنَّهُ عَبْدُهُ وَرَسُولُهُ ثُمَّ سَاقَ أَحْمَدُ بْنُ يُونُسَ خُطْبَةَ النَّبِيِّ ﷺ
