Our Prophet (saas) says; "whoever of you lives to see him, let him crawl over snow to him and join him". What is meant here is; "Do not give up your service just because the weather is cold." "If you have sensed who Mahdi (pbuh) is, if you have wholeheartedly attached yourself to the Mahdi (pbuh), you should continue your activities." That is the meaning of it. Sometimes cold weather might cause people to retract. You should not make cold, winter or the snow an excuse, you should continue your service. - Harun Yahya
