The Prophet (ﷺ) prayed at solar eclipse; he recited from the Qur'an and then bowed; then he recited from the Qur'an and then bowed; he then recited from the Qur'an and bowed; he then recited fromt eh Qur'an and bowed. Then he prostrated himself and performed the second rak'ah similar to the first.
Sunan Abi Dawud Book 3, Hadith 23
← Previous Hadith An eclipse of the sun took place in the time of the Messenger of Allah (ﷺ). The Prophet (ﷺ) led them in prayer. He recited one of the long surahs, bowing five times and prostrating himself twice. He then stood up for the second rak'ah, recited one of the long surahs, bowed five times, prostrated himself twice, then sat where he was facing the qiblah and made the supplication till the eclipse was over.

Sunan Abi Dawud Book 3, Hadith 22 Next Hadith → 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).
