Surah Al-Anfal Verse 35 - English Translation by Shabbir Ahmed
Surah Al-Anfalوَمَا كَانَ صَلَاتُهُمۡ عِندَ ٱلۡبَيۡتِ إِلَّا مُكَآءٗ وَتَصۡدِيَةٗۚ فَذُوقُواْ ٱلۡعَذَابَ بِمَا كُنتُمۡ تَكۡفُرُونَ
What is their worship at the House of Allah but whistling and clapping? Therefore it is said to them, "Taste of the Retribution for your rejection of the Truth." (Any people who plunge in ritualistic worship, trail behind in action and incur suffering)
