Sunan an-Nasa'i, Volume 2, Book 16, Hadith 1461 (DarusSalam) ⓘ

'Abdur-Rahman bin Samurah said: "While I was (practicing) shooting some arrows in Al-Madinah, the sun became eclipsed. I gathered up my arrows and said: 'I want to see what the Messenger of Allah will say about the eclipse of the sun.' So I came to him from behind when he was in the masjid, and he started to say the tasbih and takbir and to supplicate until the eclipse was over. Then he stood up and prayed two rak'ahs with four prostrations."

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ، قَالَ حَدَّثَنَا أَبُو هِشَامٍ، - وَهُوَ الْمُغِيرَةُ بْنُ سَلَمَةَ - قَالَ حَدَّثَنَا وُهَيْبٌ، قَالَ حَدَّثَنَا أَبُو مَسْعُودٍ الْجُرَيْرِيُّ، عَنْ حَيَّانَ بْنِ عُمَيْرٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ سَمُرَةَ، قَالَ بَيْنَا أَنَا أَتَرَامَى، بِأَسْهُمٍ لِي بِالْمَدِينَةِ إِذِ انْكَسَفَتِ الشَّمْسُ فَجَمَعْتُ أَسْهُمِي وَقُلْتُ لأَنْظُرَنَّ مَا أَحْدَثَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي كُسُوفِ الشَّمْسِ فَأَتَيْتُهُ مِمَّا يَلِي ظَهْرَهُ وَهُوَ فِي الْمَسْجِدِ فَجَعَلَ يُسَبِّحُ وَيُكَبِّرُ وَيَدْعُو حَتَّى حُسِرَ عَنْهَا - قَالَ - ثُمَّ قَامَ فَصَلَّى رَكْعَتَيْنِ وَأَرْبَعَ سَجَدَاتٍ ‏‏.‏‏
