Making wudhu with cold water
Q: I came across a hadith in which making a complete wudu under difficult circumstances is praiseworthy ("إسباغ الوضوء على المكاره"); one interpretation being when the water is cold. Can we choose to make wudu with cold tap water with the intention of earning this extra reward, even though warm water is also available? Or is the reward only when no warm alternative is available at all?
