2. Al-Baqara (The Cow)

Surah: 2   Aya: 114

114. Waman athlamu mimman manaAAa masajida Allahi an yuthkara feeha ismuhu wasaAAa fee kharabiha ola-ika ma kana lahum an yadkhulooha illa kha-ifeena lahum fee alddunya khizyun walahum fee al-akhirati AAathabun AAatheemun
  

  Translation

114. And who is more unjust than those who forbid that Allâh's Name be glorified and mentioned much (i.e. prayers and invocations, etc.) in Allâh's Mosques and strive for their ruin? It was not fitting that such should themselves enter them (Allâh's Mosques) except in fear. For them there is disgrace in this world, and they will have a great torment in the Hereafter.
