Al-Baqarah (The Cow)
Surah 2 · Verse 114
And who is more unjust than one who prevents (people from) the mosques of Allah, that His name should be remembered in them and strives to ruin them. (In fact) it was not fit for them to enter the (mosques) except in fear. There is disgrace for them in the world and there is a great punishment for them in the hereafter.
“Mosques are meant for offering Salat with the aim of remembering Allah (SWT) (Chapter: 20 Verse 14). Enemies of Islam probably thought that they could turn away Muslims from Islam either by stopping them from entering Mosques or directly ruining the Mosques. So Allah (SWT) is questioning as to who is more unjust than one who does this when it was actually required of them to enter Mosques fearing Him, He therefore declares that for such people there will be disgrace in this world and severe punishment in the hereafter.”
