197. Chapter: On two quick rak'ats for Fajr and clarification of what is recited in them and their time

1104. 'A'isha reported that the Prophet, may Allah bless him and grant him peace, used to pray two quick rak'ats between the adhan and the iqama for the Subh prayer." [Agreed upon]

In one variant of both al-Bukhari and Muslim, "He used to pray the two rak'ats of Fajr when he heard the adhan. He would make them so short that I would say, 'Did he recite the Umm al-Qur'an [the Fatiha} in them?'"

In a variant of Muslim, "He used to pray the two rak'ats of Fajr when he heard the adhan and made them short." In one variant, "When Fajr appeared."

1105. Hafsa said that when the mu'adhdhin withdrew to call the adhan of Subh and daybreak appeared, the Messenger of Allah, may Allah bless him and grant him peace, prayed two short rak'ats before the iqama of the prayer was given. [Agreed upon]

1106. Ibn 'Umar said, "The Prophet, may Allah bless him and grant him peace, used to pray the night prayers two by two and then do the witr with one rak'at. He would pray two rak'ats before the morning prayer with the adhan still echoing in his ears." [Agreed upon]

1107. Ibn 'Abbas reported that the Messenger of Allah, may Allah bless him and grant him peace, used to recite the following ayat from al-Baqara in the first of the two rak'ats of Fajr, "Say: 'We believe in Allah and what has been sent down to us...," (W135; H136), and in the last, "We believe in Allah. Bear witness that we are Muslims." (W3:51; H3:52)

In one variant, in the last he recited the following ayat from Ali 'Imran, "Come to a proposition which is the same for us and you." (W3:63; H3:64) [Muslim]

1108. Abu Hurayra said that the Messenger of Allah, may Allah bless him and grant him peace, recited in the two rak'ats of Fajr, "Say: 'Unbelievers!'" (109) and "Say: He is Allah, Absolute Oneness." (112) [Muslim]

1109. Ibn 'Umar said, "I watched the Prophet, may Allah bless him and grant him peace, for a month and he used to recite in the two rak'ats of Fajr, 'Say: Unbelievers!,' and 'Say: He is Allah, Absolute Oneness.'" [at-Tirmidhi]
