Hadith 338

Bulugh al-Maram

Book 2: The Book of Prayer
زَادَ أَحْمَدُ: { إِلَّا اَلْمَغْرِبَ فَإِنَّهَا وِتْرُ اَلنَّهَارِ, وَإِلَّا اَلصُّبْحَ, فَإِنَّهَا تَطُولُ فِيهَا اَلْقِرَاءَةُ } 1‏ .‏
Ahmad added, 'Except the Maghrib (prayer) for it is the Witr (prayer) of the day; and except the Fajr (prayer), since the recitation (of the Qur'an) is prolonged in it.'
