Surah Al-Mai'dah (The Spread Table), Verse 58

وَاِذَا نَادَیْتُمْ اِلَی الصَّلٰوةِ اتَّخَذُوْهَا هُزُوًا وَّلَعِبًا ذٰلِكَ بِاَنَّهُمْ قَوْمٌ لَّا یَعْقِلُوْنَ ۟

Wa izaa naadaitum ilas Salaatit takhazoohaa huzu wan'w wa la'ibaa; zaalika biannnahum qawmul laa ya'qiloon

“When ye proclaim your call to prayer they take it (but) as mockery and sport; that is because they are a people without understanding.”

Quran 5:58 (Yusuf Ali Translation)
