Musnad Ahmad Hadith 24670

It is narrated from Aisha (may Allah be pleased with her) that when there was a solar eclipse during the blessed era of the Prophet (ﷺ), the Prophet (ﷺ) ordered ablution, the announcement for prayer was made that the prayer is ready, then he stood up and performed a long standing in prayer and most likely recited Surah Al-Baqarah in it, then performed a long bowing (ruku), then after saying "Sami Allahu liman Hamidah" he stood for quite a while as before and did not go into prostration but performed ruku again, then went into prostration, and in the second rak'ah he did the same, that is, performed two ruku in each rak'ah, then sat in Tashahhud, and during this the solar eclipse ended.
