'Ikrima said that when Ibn ‘Abbas was told that a certain wife of the Prophet had died, he prostrated himself. Someone asked him why he made prostration at such a time, and he replied, “God’s Messenger told us to prostrate ourselves when we saw a sign, and what sign is greater than the departure of the Prophet's wives?”
Ubayy b. Ka'b said that when an eclipse of the sun took place in the time of God’s Messenger he led them in prayer, reciting one of the long suras, bowing five times and prostrating himself twice. He then stood up for the second rak'a, recited one of the long suras, bowed five times, prostrated himself twice, then sat where he was facing the qibla and made supplication till the eclipse passed.
