Hadith 1480

‘A’isha said there was an eclipse of the sun in the time of God’s Messenger, and he sent one to summon the people to congregational prayer. He then went forward and prayed two rak'as in which he bowed four times and prostrated himself four times. ‘A’isha said, “I never performed a bow or a prostration which was longer than it.” (Bukhari and Muslim.)
