Sayyiduna Kharijah bin Hudhafah al-Adawi (may Allah be pleased with him) said: I heard the Prophet (peace and blessings be upon him) say: "Allah Almighty has aided you with a prayer that is better for you than red camels; its time is between Isha and the rising of dawn, that is, witr."
Imam al-Bukhari (may Allah have mercy on him) said: It is not known that the narrators of its chain heard from one another.
