Should beggars be banned in the mosques?

I do not know of anything wrong with that, and I do not know
of any evidence for those who ban them, but if the beggars step over
people’s necks and walk between the rows, then they should be stopped from
doing that, because by doing that they are disturbing the worshippers.
Similarly at the time of the Friday khutbah, they should be prevented
because it is obligatory for them and other worshippers to listen
attentively and because their begging at this time will distract others from
listening to the khutbah. End quote.
