Miqdam Abu Karimah Radiyallahu 'anhu narrates that Rasulullah Sallallahu 'alaihi wasallam said: If the guest of people remains without hospitality till the morning, then it is the duty of every Muslim to help him, in taking from the crops and property of the host to the extent of the entertainment of one night. (Abu Dawud: 3751)
Note: This is a situation where there is no provision with the guest
and he is thus constrained. Otherwise out of kindness and courtesy
fulfilling a guest's needs is his right. (Mazahir Haque)
