Allah's Messenger (ﷺ) (p.b.u.h) said, "Keys of the unseen knowledge are five which nobody knows but Allah . . . nobody knows what will happen tomorrow; nobody knows what is in the womb; nobody knows what he will gain tomorrow; nobody knows at what place he will die; and nobody knows when it will rain."
Sahih al-Bukhari Book 15, Hadith 34
← Previous Hadith Allah's Messenger (ﷺ) led the morning prayer in Al-Hudaibiya and it had rained the previous night. When the Prophet (p.b.u.h) had finished the prayer he faced the people and said, "Do you know what your Lord has said?" They replied, "Allah and His Apostle know better." (The Prophet (ﷺ) said), "Allah says, 'In this morning some of My worshipers remained as true believers and some became non-believers; he who said that it had rained with the blessing and mercy of Allah is the one who believes in Me and does not believe in star, but he who said it had rained because of such and such (star) is a disbeliever in Me and is a believer in star.' "

Sahih al-Bukhari Book 15, Hadith 33 Next Hadith → We were with Allah's Messenger (ﷺ) when the sun eclipsed. Allah's Messenger (ﷺ) stood up dragging his cloak till he entered the Mosque. He led us in a two-rak`at prayer till the sun (eclipse) had cleared. Then the Prophet (p.b.u.h) said, "The sun and the moon do not eclipse because of someone's death. So whenever you see these eclipses pray and invoke (Allah) till the eclipse is over."
