Aya number 35 of surat Al-Anfal

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

وَمَا كَانَ صَلَاتُهُمْ عِنْدَ الْبَيْتِ إِلَّا مُكَاءً وَتَصْدِيَةً فَذُوقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُونَ [٣٥]

Translation: English - Sahih International

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