7. A person points out that many Deobandi Masaajid have TV's installed for Salaah times and notices. He says that when such high ranking 'Ulama have allowed TV's to be put up in the Masjid, and we do not see any other Ulama objecting to it (and also Ulama continue giving bayaans and having programs at such Masaajid) then it is therefore permissible for one to sell TV's. He adds that if Masjid funds can be used to buy a TV to put up in a Masjid, then why can't he sell TV's as the dual purpose of the TV is now clear with its incorporation in even the Masjid. Is this correct?
