What did the Prophet Muhammad (saw) say to the woman when he found out that she was doing excessive praying?
      Narrated 'Aisha:                          Once the Prophet came while a woman was sitting with me. He said, "Who     is she?" I replied, "She is so and so," and told him about her      (excessive) praying. He said disapprovingly, "Do (good) deeds which is     within your capacity (without being overtaxed) as Allah does not get      tired (of giving rewards) but (surely) you will get tired and the best     deed (act of Worship) in the sight of Allah is that which is done      regularly."
