The word(s) "congregation" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) And when thou seest those who meddle with Our revelations, withdraw from them until they meddle with another topic. And if the devil cause thee to forget, sit not, after the remembrance, with the congregation of wrong-doers.

(2) O ye who believe! When the call is heard for the prayer of the day of congregation, haste unto remembrance of Allah and leave your trading. That is better for you if ye did but know.
