Narrated Kharijah bin Hudhaifah (RA):
Allah's Messenger (ﷺ) said: "Allah the Exalted has given you an extra prayer which is better for you than the red camels (high breed camels)." We asked, "What is it O Allah's Messenger." He said, "The Witr between the 'Isha' prayer and up till the break of dawn." [Reported by al-Khamsah except an-Nasa'i and al-Hakim graded it Sahih (authentic)].
