Mosque

The word masjid is derived from the verb sajada 'to do sujud' and is of pre-Islamic use. It signifies 'a place of sujud'.

S 7:29 Say: My lord has commanded equity and set your faces at every mosque and invoke him sincere towards him in the religion. As he began you do you return.

S 7:31 Banu Adam, take your adornment at every mosque and eat and drink and do not exceed. He does not love the exceeders.

The 'Banu Adam' are human beings in general and aren't all Muslims. And as the original masajid were places of doing sujud, does this verse apply to churches and to even Hindu, etc., temples?

The plural occurs in three verses.

S 2:114 And who is more unjust than he who has prevented the mosques of Allah, his name to be mentioned in them and has striven for their ruin? Those, theirs was not to enter them except terrified. Theirs in the dunya is disgrace and theirs in the hereafter is great torture.

Christians supposedly worship Allah. If a Muslim damages a church in which Arabic is spoken, is he possibly preventing Allah's name from being mentioned?

S 9:17 It was not for the mushrikun to restore the mosques of Allah witnessing against themselves in kufr. Those, their deeds have become worthless and in the fire they abide indefinitely.

S 9:18 Only one who has believed in Allah and the last day and has performed salat and given the zakat and has not feared but Allah restores the mosques of Allah. Then perhaps those that they be of the guided.
