Sahih Bukhari Volume 2, Book 18, Hadith Number 153.
Narated By Al-Mughira bin Shu’ba : “The sun eclipsed in the life-time of Allah’s Apostle on the day when (his son) Ibrahim died. So the people said that the sun had eclipsed because of the death of Ibrahim. Allah’s Apostle said, “The sun and the moon do not eclipse because of the death or life (i.e. birth) of some-one. When you see the eclipse pray and invoke Allah.”
