On one occasion, Sayyiduna Uthman (may Allah be pleased with him) delivered a sermon from the pulpit and said: I am narrating to you a hadith which I heard from the Prophet (peace and blessings be upon him); it is not out of miserliness that I would refrain from conveying it to you. I heard the Messenger of Allah (peace and blessings be upon him) say: Guarding for one night in the path of Allah is superior to standing in prayer and fasting during the day for a thousand nights.
