Q 1 and 2: What
is the ruling on the congregational Salah? Does the term "congregational" refer to the congregation observed in the Masjid (mosque)?
What is the ruling on a man having no excuse not to offer prayers in the Masjid though living nearby?
Offering the congregational Salah is obligatory and whoever abandons it without a justifiable reason is sinful. (Part No. 7; Page No. 284) When using the term "congregational" in a general sense, it refers to the congregation observed in the Masjid, if it is established, and a Muslim is able to join it.
