Sahih Ibn Khuzaymah

Lady Aisha (may Allah be pleased with her) narrates that during the blessed time of the Messenger of Allah (peace and blessings be upon him), there was a solar eclipse, so the Prophet (peace and blessings be upon him) led the (eclipse) prayer and made the companions stand for a very long time. The Prophet (peace and blessings be upon him) made the companions stand, then performed bowing (ruku‘), then made them stand again, then performed bowing again; in this way, the Prophet (peace and blessings be upon him) performed two rak‘ahs, with three bowings in each rak‘ah. The Prophet (peace and blessings be upon him) performed the third bowing, then prostrated, until, due to the long standing that day, some companions fainted and buckets of water were poured over them. Whenever the Prophet (peace and blessings be upon him) said the takbir, he would say « اللهُ أَكْبَرُ », and when he raised his head from bowing, he would say « سَمِعَ اللهُ لِمَنْ حَمِدَهُ », so the Prophet (peace and blessings be upon him) did not finish the prayer until the sun became bright. Then the Prophet (peace and blessings be upon him) stood and praised and glorified Allah, and said: “Indeed, the sun and the moon do not eclipse because of the death or life of any person, but these two are among the signs of Allah with which Allah frightens His servants. So when you see them eclipsed, hasten to the remembrance of Allah until they become bright and clear.”
