There are some local members of our masjid, who are associated with Tabligh, who have breakfast in the masjid after Fajr Salah. Keep in mind that there are all local members of the Masjid, for whom using the lights and gas is permissible. Please guide us through the light of Quran and Sunnat.
الجواب حامدا و مصلیا
It is not permissible for the local members to eat or sleep in the masjid. This must be avoided. However, travelers are allowed to eat and sleep in the masjid. It is also not permissible for the local members of the masjid to heedlessly use the lights or gas of the masjid. They should only be used to the extent of need.
