8 glad tidings to one who offers Fajr Prayer in Congregation every day

1. Having a perfect light on the Day of Judgment.

Narrated Buraydah ibn al-Hasib:

The Prophet (pbuh) said: Give good tidings to those who walk to the mosques in darkness for having a perfect light on the Day of Judgment.

2. The two Rak’ah before the dawn (Fajr) prayer are better than this world and all it contains.
Aishah (May Allah be pleased with her) reported:

The Prophet (ﷺ) said,

“The two Rak’ah before the dawn (Fajr) prayer are better than this world and all it contains.”

3. Attendance of the Angel

أَقِمِ الصَّلَاةَ لِدُلُوكِ الشَّمْسِ إِلَىٰ غَسَقِ اللَّيْلِ وَقُرْآنَ الْفَجْرِ ۖ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا

Perform As-Salat (Iqamat-as-Salat) from mid-day till the darkness of the night (i.e. the Zuhr, ‘Asr, Maghrib, and ‘Isha’ prayers), and recite the Quran in the early dawn (i.e. the morning prayer). Verily, the recitation of the Quran in the early dawn is ever witnessed (attended by the angels in charge of mankind of the day and the night).
Quran 17:78

4. Protection from hell fire

Abu Zuhair ‘Umarah Ruwaibah (May Allah be pleased with him) reported:

I heard the Messenger of Allah (ﷺ) saying:

“He who performs Salat (prayers) before the rising of the sun and before its setting, will not enter the Hell.”

[Muslim]

5. Seeing Allah (S.W)

Narrated Jarir:
We were sitting with the Prophet (ﷺ) and he looked at the moon on the night of the full-moon and said,

”

You people will see your Lord as you see this full moon, and you will have no trouble in seeing Him, so if you can avoid missing (through sleep or business, etc.) a prayer before sunrise (Fajr) and a prayer before sunset (`Asr) you must do so.”

Reference : Sahih al-Bukhari 7434

6. Reward for Qiyaam layl

Uthman bin ‘Affan (May Allah be pleased with him) reported:

I heard the Messenger of Allah (ﷺ) saying:

“One who performs ‘Isha’ prayer in congregation, is as if he has performed Salat for half of the night. And one who performs the Fajr prayer in congregation, is as if he has performed Salat the whole night.”

[Muslim]

7. Reward for Hajj and Umrah

Anas bin Malik narrated that :

the Messenger of Allah said:

“Whoever prays Fajr in congregation, then sits remembering Allah until the sun has risen, then he prays two Rak’ah, then for him is the reward like that of a Hajj and Umrah.” He said: “The Messenger of Allah said: ‘Complete, complete, complete.'”

Reference : Jami` at-Tirmidhi 586

8. Protection of Allah

Jundub bin Sufyan (May Allah be pleased with him) reported:

The Messenger of Allah (ﷺ) said,

“He who offers the dawn (Fajr) prayers will come under the Protection of Allah. O son of Adam! Beware, lest Allah should call you to account in any respect from (for withdrawing) His Protection.”
