Surah Al-Anfal, Verse 35

وَمَا كَانَ صَلَاتُهُمۡ عِندَ ٱلۡبَيۡتِ إِلَّا مُكَآءٗ وَتَصۡدِيَةٗۚ فَذُوقُواْ ٱلۡعَذَابَ بِمَا كُنتُمۡ تَكۡفُرُونَ٣٥

wamā kāna ṣalātuhum ʿinda l-bayti illā mukāan wataṣdiyatan fadhūqū l-ʿadhāba bimā kuntum takfurūna

And their prayer at the House [i.e., the Kaʿbah] was not except whistling and handclapping. So taste the punishment for what you disbelieved [i.e., practiced of deviations].
