Narrated Ibn 'Umar (RA):

The Prophet (ﷺ) said: "The twilight is the redness." [Reported by ad-Daraqutni. Ibn Khuzaimah graded it Sahih (authentic) and others graded it Mawquf (a saying of a Companion)].

وَعَنْ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا; عَنْ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-قَالَ: { اَلشَّفَقُ اَلْحُمْرَةُ } رَوَاهُ اَلدَّارَقُطْنِيُّ وَصَحَّحَ اِبْنُ خُزَيْمَةَ وَغَيْرُهُ وَقْفَهُ [1]‏ .‏
