The ruling on the greeting of the mosque in an Islamic center located on the second floor of the mosque

The questioner:
This professor says: We have an Islamic center for non-Muslim communities in our city, and it is on the second floor of the mosque. Is it obligatory for whoever comes to the center to perform the greeting of the mosque? And is it obligatory for him to sit on the chairs?

The Shaykh:
Here.

The questioner:
We have an Islamic center in our city for the purpose of calling non-Muslims to Islam, and it is on the second floor of the mosque. Is it obligatory for whoever comes to the center if he only sits on a chair?

The Shaykh:
If the mosque was established for those who want the lower floor of the mosque, and the upper floor was made into a center, and no mosque was found, and it is not for the people of the mosque, but was made into an independent center that does not have the ruling of a mosque, then it does not have the ruling of a mosque; one does not perform the greeting in it, nor does one pray two rak'ahs upon entering. However, if he intended it to be a mosque, but allowed a center for da'wah, or a circle for knowledge, or for the recitation of the Qur'an to be held in it, then it is like the mosque; one performs the greeting in it, and if he enters, he prays two rak'ahs, just as in the mosque, because actions are by intentions. For example, if a person builds a mosque and makes the lower floor a shop and the upper floor a mosque, or the reverse, making the lower floor a mosque and the upper floor a residence, it is according to the intention. So the upper part is a mosque and the lower part is a mosque, or the reverse, according to your intention.

The questioner:
On Friday, he prays on the second floor, and during the sermon, they believe.

The Shaykh:
It is valid in front of the mosque, it is similar.

The questioner:
There is nothing except Friday.

The Shaykh:
If it was taken by Allah, but they were allowed to establish the center, they validate it in the mosque.

The questioner:
The one you are sitting and writing in, O water.

The Shaykh:
One performs the greeting in it and prays in it, and whoever enters prays two rak'ahs, just as in the mosque, because the center follows the mosque. The common practice is like this, because the center follows the knowledge. It is possible for the da'wah to follow the knowledge, and the mosques are the place of knowledge and the place of circles of knowledge.
