وَمَنْ أَظْلَمُ مِمَّن مَّنَعَ مَسَاجِدَ اللَّهِ أَن يُذْكَرَ فِيهَا اسْمُهُ وَسَعَىٰ فِي خَرَابِهَا ۚ أُولَٰئِكَ مَا كَانَ لَهُمْ أَن يَدْخُلُوهَا إِلَّا خَائِفِينَ ۚ لَهُمْ فِي الدُّنْيَا خِزْيٌ وَلَهُمْ فِي الْآخِرَةِ عَذَابٌ عَظِيمٌ (114)
(2:114) And who could be a greater wrongdoer than the one who forbids the mention of Allah's name in places of worship and strives for their ruin? Such people do not deserve to enter the places of worship, and, if they enter at all, they should do so in fear; *114 for there is ignominy for them in this world and an awful punishment in the Hereafter.
*114). Places of worship should properly remain in the custody of devout and God-fearing people, so that even if bad people did go there they would be deterred from committing misdeeds through fear of punishment. This is a subtle reference to the wrong perpetrated by the unbelievers of Makka, who had barred their own compatriots - the Muslims - from worshipping in the House of God.
