There are a number of hadith that state the virtues of observing the sunnah prayer at dawn time. For example: ‘Aishah relates that the Prophet sallallahu alehi wasallam said about the two rak’at before the fajr “They are dearer to me than the whole world.” This is related by Ahmad, Muslim, and at-Tirmizhi. Abu Hurairah reports that the Prophet said: “Do not leave the two rak’at of the fajr, even if you are being attacked by a cavalry.” This is confirmed by Ahmad, Abu Dawud, al-Baihaqi, and at-Tahawi. The message of the hadith is that one should not leave the two rak’at of the fajr no matter what the excuse, even while under enemy attack or under most trying conditions. ‘Aishah says: “The Messenger of Allah was not so particular about observing any supererogatory prayer as he was in observing the two rak’at before salatul fajr.” This is related by al-Bukhari, Muslim, Ahmad, and Abu Dawud. She also reports that the Prophet said: “The two rak’at of the fajr are better than this world and all it contains.” This is reported by Ahmad, Muslim, at-Tirmizhi, and an-Nasa’i. Ahmad and Muslim also record that she said: “I have never seen him [the Prophet] more in haste to do a good deed than he was to perform the two rak’at before the morning [prayer].”
