Surah Al-Ma'idah, ayah 58

وَإِذَا نَادَيۡتُمۡ إِلَى ٱلصَّلَوٰةِ ٱتَّخَذُوهَا هُزُوٗا وَلَعِبٗاۚ ذَٰلِكَ بِأَنَّهُمۡ قَوۡمٞ لَّا يَعۡقِلُونَ ٥٨

Wa idhā nādaytum ilas-salawātit-takhadhūhā huzuwan wala'iban dhālika bi annahum qawmul lā ya'qilūn

And when you call to prayer, they take it in ridicule and amusement. That is because they are a people who do not use reason.
