Hadith 2407
Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings of Allah be upon him): "Witr is a right; whoever wishes to perform five witr may do so, whoever wishes to perform three witr may do so, whoever wishes to perform one witr may do so, and whoever finds it difficult to perform it should recite it with gestures."
