فَجْرٌ
1.
[Daybreak; dawn;] the light of morning; (Mgh, K;) because it is a cleaving of the darkness from before the light; (Mgh;) i. e., the redness of the sun in the darkness of night; (K;) the فَجْر in the end of the night is like the شَفَق in the beginning thereof: (S, O:) it is twofold: the first is called الفَجْرُ الكَاذِبُ [the false dawn]; that which rises without extending laterally, (المُسْتَطِيلُ, Mgh, Msb,) which appears black, presenting itself like an obstacle (مُعْتَرِضًا) [on the horizon]: (Msb:) [see ذَنَبُ السِّرْحَانِ, in article سرح:] the second is called الفَجْرُ الصَّادِقُ [the true dawn]; which is the rising and spreading [dawn], (المُسْتَطِيرُ, Mgh, Msb,) which appears rising, and fills the horizon with its whiteness; and this is what is called عَمُودُ
الصُّبْحِ; rising after the former has disappeared; and by its rising the day commences, and everything by which fasting would be broken becomes unlawful to the faster. (Msb.)

الفَجْرُ and البَحْرُ [in a saying mentioned voce بَحْرٌ, the former here written الفَجَرُ, and said to be مُحَرَّكَة, but apparently by mistake, for it is afterwards written الفَجْرُ,] are metonymically applied to (tropical:) The troubles of the present state of existence. (TA.)
