Sura al-Anfāl 8:35

وَمَا كَانَ صَلَاتُهُمْ عِندَ ٱلْبَيْتِ إِلَّا مُكَآءً وَتَصْدِيَةً فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ

wa-mā kāna ṣalātuhum ʿinda l-bayti illā mukāʾan wa-taṣdiyatan fa-dhūqū l-ʿadhāba bi-mā kuntum takfurūna

Their prayer at the House (of Allah) is nothing but whistling and clapping of hands: (Its only answer can be), "Taste ye the penalty because ye blasphemed."

Sura al-ʿAbasa 80:6

فَأَنتَ لَهُۥ تَصَدَّىٰ

fa-anta lahu taṣaddā

To him dost thou attend;
