What are the regulations concerning a person's stay in the mosque, their use of its facilities such as the computer and library, their handling of the two rak'ahs for greeting the mosque when entering repeatedly, the permissibility of using the mosque's kitchen for preparing communal or personal food, and the extent to which it is permissible to offer refreshments to children inside the mosque as an encouragement for them?

First: There is no harm in you staying in rooms connected to the mosque to teach children and use modern technologies, nor in offering them biscuits and juices, while teaching them to maintain the cleanliness of the mosque.

Second: If a worshiper leaves the mosque with the intention of returning shortly, they are not obligated to pray Tahiyyat al-Masjid (mosque greeting prayer) upon their return; the first prayer suffices, like someone who leaves for ablution or to fetch a book. However, if a long time passes, they are obligated to pray.

Third: Rooms connected to the mosque take the ruling of the mosque, and Tahiyyat al-Masjid is obligatory in them, and menstruating and post-natal women are prohibited from them if they are prepared to be part of it for prayer. However, if they are prepared as annexes for education or meetings, they do not take the ruling of the mosque. If the intention is unknown, the default is that whatever is within the mosque's fence and has a door leading to it takes its ruling.

Fourth: There is no harm in using the kitchen located in the mosque for communal Iftar in Ramadan or for preparing tea and food for guests. However, it should not be made a permanent place for cooking food to avoid the spread of odors in the mosque, unless the kitchen is separated from the mosque by a wall.
