Fajr, The Dawn Prayer
When
Begins at true dawn (al-fajr al-sadiq), the moment the horizontal white light first spreads across the eastern horizon, and ends at sunrise. Performed before the sun's disc appears. It is the only daily prayer prayed while it is still dark, marking the transition from night to day.
Structure
Two rak'ahs of fard. Preceded by two rak'ahs of confirmed Sunnah (Sunnah al-Fajr), which the Prophet ﷺ never abandoned at home or on journey, calling it "better than the world and all it contains." Recitation is aloud (jahri) for both rak'ahs.
Story
Like all five prayers, Fajr was ordained on the Night Journey when the Prophet ﷺ ascended through the seven heavens and Allah originally prescribed fifty daily prayers, eventually reduced to five (with the reward of fifty). Specifically about Fajr, Jibril (as) led the Prophet ﷺ in this prayer at the Ka'bah twice on consecutive days to teach its time: once at the very beginning of dawn and once just before sunrise, then said: "The time is between these two."
Significance
Fajr is described in the Quran as "witnessed", the angels of the night and the angels of the day both attend it together, with no other prayer sharing this honour. It is the dividing line between the sincere believers and the hypocrites, who find it heaviest. It opens the day with the surrender of one's faculties to Allah before the worldly demands begin, and the Prophet ﷺ said the one who prays it is "in the protection of Allah" until evening.
Quranic proof
"Establish prayer at the decline of the sun [from its meridian] until the darkness of the night, and the recitation of dawn (qur'an al-fajr). Indeed, the recitation of dawn is ever witnessed." (Al-Isra' 17:78). The phrase "qur'an al-fajr" specifically denotes the Fajr prayer's lengthy recitation, and "ever witnessed" refers to the night and day angels both being present.
Hadith proof
The Prophet ﷺ said: "Whoever prays the Fajr prayer is in the protection of Allah." (Muslim 657). He also said: "The two cool prayers, whoever prays them will enter Paradise." (Bukhari 574, Muslim 635). When asked about the "two cool prayers," the Companions explained: Fajr and Asr. Abu Hurayrah (ra) reported that the angels of the night and the angels of the day gather at Fajr, ascend together, and the angels of the day stay; this is the witnessing referred to in the verse.
Recitation
Recited aloud (jahri). The Sunnah is to lengthen the recitation here more than any other prayer, often 60 to 100 verses in total. The Prophet ﷺ frequently recited Surah Qaf (50), al-Waqi'ah (56), al-Mursalat (77), at-Takwir (81), or similar surahs of the latter half of the Quran. On Friday Fajr specifically, the Sunnah is to recite Surah as-Sajdah (32) in the first rak'ah and Surah al-Insan (76) in the second, the only two surahs reported to contain Sunnah sujud al-tilawah in this prayer.
What is Sunnah to say
In the two Sunnah rak'ahs of Fajr, the Prophet ﷺ recited very short surahs: in the first rak'ah Surah al-Kafirun (109) or "Qulu amanna billahi..." (2:136), and in the second Surah al-Ikhlas (112) or "Qul ya ahla al-kitab..." (3:64). Make the two Sunnah rak'ahs short and the two fard long. Between the two Sunnah and the fard, supplicate quietly; the dawn is one of the times du'a is most accepted. Before the prayer, on rising from sleep, say "Alhamdu lillahi-lladhi ahyana ba'da ma amatana wa ilayhin-nushur".
Additional adhkar
After the fard salam, in addition to the universal post-prayer adhkar: the morning adhkar (adhkar al-sabah) are due now and remain valid until sunrise. Among them: Ayat al-Kursi, the three Quls each three times with blowing into the palms, "Hasbiyallahu la ilaha illa huwa, 'alayhi tawakkaltu wa huwa Rabbul-'Arshil-'Azim" (seven times), and "Allahumma bika asbahna wa bika amsayna...". After completing the morning adhkar, remain seated in the place of prayer until sunrise, then pray two rak'ahs of "Ishraq"; the Prophet ﷺ said this carries the reward of a complete Hajj and Umrah.
Virtues
Praying Fajr in congregation has the reward of standing the entire night in prayer (Muslim 656). Standing in prayer between Fajr and sunrise is described by the Prophet ﷺ as "more beloved to me than freeing four slaves." The morning hours after Fajr are blessed: the Prophet ﷺ supplicated, "O Allah, bless my nation in their early mornings." The hypocrites are identified by their inability to attend Fajr, "the heaviest prayers on the hypocrites are Isha and Fajr; if they knew what they contain, they would crawl to them." (Bukhari 657, Muslim 651).
Timing notes
Avoid praying any voluntary prayer (other than greeting the mosque or the omitted Sunnah al-Fajr) from sunrise until the sun has fully risen and risen "the height of a spear" (approximately 15-20 minutes after sunrise). If a person misses Fajr by sleep or genuine forgetfulness, he prays it as soon as he wakes, the Prophet ﷺ did this once on a journey when the army overslept, and said: "There is no failure (lit. 'no negligence') in sleep; failure is in wakefulness." (Muslim 681). The two Sunnah rak'ahs can also be prayed immediately after the fard if missed beforehand, or after sunrise (Tirmidhi 423).
