Quran 8:35 — Surah Al-Anfal, ayah 35

وَمَا كَانَ صَلَاتُهُمۡ عِندَ ٱلۡبَيۡتِ إِلَّا مُكَآءٗ وَتَصۡدِيَةٗۚ فَذُوقُواْ ٱلۡعَذَابَ بِمَا كُنتُمۡ تَكۡفُرُونَ

And their prayer at the House was not except whistling and handclapping. So taste the punishment for what you disbelieved

Molitva njihova pored Hrama svodi se samo na zviždanje ili pljeskanje rukama; zato kaznu iskusite, jer ne vjerujete.
