Salam brother Ansar,

I asked the Sheik here and he says a hadeeth like this does exists, it goes something like this it is about Abu Bakir (ra) when he was appointed the ameer (leader) of a group who where traveling and he said along these lines my job as ameer is to serve the people. He gave me the reference but I couldnt write it down but inshallah I will try and get it for you on Sunday after work.
