The sun eclipsed and the Prophet (ﷺ) got up, being afraid that it might be the Hour (i.e. Day of Judgment). He went to the Mosque and offered the prayer with the longest Qiyam, bowing and prostration that I had ever seen him doing. Then he said, "These signs which Allah sends do not occur because of the life or death of somebody, but Allah makes His worshipers afraid by them. So when you see anything thereof, proceed to remember Allah, invoke Him and ask for His forgiveness."
Sahih al-Bukhari Book 16, Hadith 18
← Previous Hadith In the lifetime of the Prophet (ﷺ) the sun eclipsed and the Prophet (p.b.u.h) stood up to offer the prayer with the people and recited a long recitation, then he performed a prolonged bowing, and then lifted his head and recited a prolonged recitation which was shorter than the first. Then he performed a prolonged bowing which was shorter than the first and then lifted his head and performed two prostrations. He then stood up for the second rak`a and offered it like the first. Then he stood up and said, "The sun and the moon do not eclipse because of someone's life or death but they are two signs amongst the signs of Allah which He shows to His worshipers. So whenever you see them, make haste for the prayer."

Sahih al-Bukhari Book 16, Hadith 17 Next Hadith → On the day of Ibrahim's death, the sun eclipsed and the people said that the eclipse was due to the death of Ibrahim (the son of the Prophet). Allah's Messenger (ﷺ) said, "The sun and the moon are two signs amongst the signs of Allah. They do not eclipse because of someone's death or life. So when you see them, invoke Allah and pray till the eclipse is clear."
