Musnad Ahmad 1153:460

'Abd al-Samad narrated to us, Sulayman ibn Kathir narrated to us, he said: al-Zuhri narrated to us, from 'Urwah, from 'Aishah, that she said: The sun eclipsed during the time of the Prophet, may Allah bless him and grant him peace. The Prophet, may Allah bless him and grant him peace, came to the place of prayer, and he said the takbir, and the people said the takbir. Then he recited and made the recitation audible, and he lengthened the standing. Then he bowed and lengthened the bowing. Then he raised his head and said: "Allah hears those who praise Him." Then he stood and recited, and he lengthened the recitation. Then he bowed and lengthened the bowing. Then he raised his head, then he prostrated. Then he stood, and he did the same in the second [rak'ah]. Then he said: "Indeed, the sun and the moon are two signs from the signs of Allah, the Mighty and Majestic. They do not eclipse for the death of anyone, nor for his life. So when you see that, hasten to the prayer."
