أَوَلَا يَعْلَمُونَ أَنَّ اللَّهَ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ
Awa laa ya'lamoona annal laaha ya'lamu maa yusirroona wa maa yu'linoon
Do they not know that God knows what they conceal and what they declare?
Yusirrūn and yuʿlinūn are a matched pair, concealing and declaring, and the Qur'an uses them together often enough that they function as a way of saying everything without listing anything. The verse is short and takes the form of a question, so it supplies no new charge and instead removes the assumption the previous scene rested on. Its placement immediately after that scene is what gives it force.
