Taukal

a  man presented  himself  before  the  prophet and  asked  what  was  right  for  him to  do  , if  he  should  tie  up  the  camel or  set  him free, 
the  prophet-salallahoalleywassalum spoke  that  he  may  keep  the  camel
-because  for  the  worldy this  life  is  heaven where  they  gain, and  for  the  believer  the  day  of  judgement is  the  moment  of  truth
