Ya'qub bin Ibrahim bin Sa'd يعقوب بن إبراهيم بن سعد بن إبراهيم · The Book of Eclipses

"The Messenger of Allah (ﷺ) said: "The sun and the moon do not become eclipsed for the death or birth of anyone, rather they are two of the signs of Allah (SWT), the Mighty and Sublime, so when you see that then pray.'"

"The sun was eclipsed during the time of the Messenger of Allah (ﷺ), and the Prophet (ﷺ) commanded a caller to call out that prayer was about to begin in congregation. So they gathered and formed rows, and he led them in prayer, bowing four times in two rak'ahs and prostrating four times."
