Sahih Bukhari Volume 2, Book 18, Hadith Number 172.
Narated By ‘Aisha : The Prophet (p.b.u.h) recited (the Quran) aloud during the eclipse prayer and when he had finished the eclipse prayer he said the Takbir and bowed. When he stood straight from bowing he would say “Sami ‘al-l-ahu Lyman hamidah Rabbana walaka-l-hamd.” And he would again start reciting. In the eclipse prayer there are four bowing and four prostrations in two Rakat. Al-Auza’i and others said that they had heard Az-Zuhi from ‘Ursa from ‘Aisha saying, “In the life-time of Allah’s Apostle the sun eclipsed, and he made a person to announce: ‘Prayer in congregation.’ He led the prayer and performed four bowing and four prostrations in two Rakat.” Narrated Al-Walid that ‘Abdur-Rahman bin Namir had informed him that he had heard the same. Ibn Shihab heard the same. Az-Zuhrl said, “I asked (‘Ursa), ‘What did your brother ‘Abdullah bin AzZubair do? He prayed two Rakat (of the eclipse prayer) like the morning prayer, when he offered the (eclipse) prayer in Median.’ ‘Ursa replied that he had missed (i.e. did not pray according to) the Prophet’s tradition.” Sulaiman bin Kathir and Sufyan bin Husain narrated from Az-Zuhri that the prayer for the eclipse used to be offered with loud recitation.
