If you pray in congregation at home or in the workplace, you do not attain the reward of praying in congregation in the mosque.

There is no specific distance defined in Shari`ah, rather that depends on `Urf (custom) or the distance within which the Adhan can be heard without a microphone.

A mosque is a place that fulfils the following conditions: 1- It has been set aside as a Waqf and is no longer the property of the one who established it. 2- General permission to pray in it has been given. 3- It is established for the purpose of offering the five daily prayers regularly and on a permanent basis.

1. It is not permissible to make lost property announcements in the mosques or to make announcements about items that have been found. 2. Whoever wants to make a lost property announcement, let him go outside the mosque, and if he writes on a piece of paper and sticks it on the outside wall of the mosque. 3. If the advertisement has to do with an act of worship, there is nothing wrong with it. But if the advertisement has to do with worldly matters, then it is prohibited.
