Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever prays the Bardayn (Fajr and ‘Asr prayers) will enter Paradise."
Authentic hadith - Narrated by Bukhari & Muslim

The Prophet (may Allah's peace and blessings be upon him) encourages the observance of the Bardayn, namely the Fajr and ‘Asr prayers. He gave glad tidings for whoever observes them in their due manner in terms of time, congregation, etc, that they would be a means of admitting him to Paradise.

  1. The merit of observing the Fajr and ‘Asr prayers; is that the Fajr occurs at the time of deep sleep and ‘Asr occurs when one is occupied with his work. Therefore, whoever observes them will observe the rest of the prayers with greater reason.
  2. The Fajr and ‘Asr prayers were called "Bardayn" because of the cold night breeze at the time of the Fajr prayer and the cold daytime breeze at the time of the ‘Asr prayer, even though it is hot at that time yet it is less hot than the time that precedes it; or they were called by way of dominance, as the sun and moon are called: the two moons.
