Hadith 2624
Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings be upon him): "The night prayer should be performed two by two, and when you intend to finish the prayer, then perform one rak'ah; the prayer you have performed will thus become odd."
