Abu Hurayra reported that the Prophet, may Allah bless him and
grant him peace, forbade gatherings in the road. They said, "Messenger
of Allah, it is hard for us to sit in our houses." He said, "If you must
sit there, then fulfil the rights of the gathering." They asked, 'What
is their right, Messenger of Allah?" He replied, "Guiding anyone who asks
for directions, returning the greeting, lowering the eye, commanding the
correct and forbidding the bad."
