Do I pray the greeting of the mosque in a mosque where Friday prayer is not held?

The questioner : We entered the mosque, O Shaykh, during the Maghrib and 'Isha' prayers. In Maghrib, I assumed the mosque was a congregational mosque where Friday and congregational prayers are held... so I entered and prayed, intending it as the two rak'ahs of the greeting of the mosque. Then, in the middle of the prayer... the Sunnah of Maghrib and the greeting, I thought the mosque was small, and in 'Isha' I made up for that by praying only the Sunnah... .

The Shaykh : I did not understand what you said!

The questioner : The mosque where we prayed Maghrib today, and where congregational prayer is not held, meaning it is not a congregational mosque! Is the greeting of the mosque prayed in it?

The Shaykh : Are you talking about a mosque you know, or one that I know?!

The questioner : The people of the town ask if he prays Friday and congregational prayer in it... No, no... .

The Shaykh : Where did you get this distinction from? Is it not a mosque?

The questioner : Friday prayer is not held in it; meaning, because the scholars did not agree.

The Shaykh : Shaykh, a mosque where Friday prayer is not held is not called a congregational mosque, but the Messenger (peace and blessings be upon him) — you know — said: , but we distinguish between a mosque and a prayer place! Not between a mosque and a congregational mosque; for both are mosques!
