Surah An-Nisa, ayah 63

أُوْلَٰٓئِكَ ٱلَّذِينَ يَعۡلَمُ ٱللَّهُ مَا فِي قُلُوبِهِمۡ فَأَعۡرِضۡ عَنۡهُمۡ وَعِظۡهُمۡ وَقُل لَّهُمۡ فِيٓ أَنفُسِهِمۡ قَوۡلَۢا بَلِيغٗا ٦٣

Ulā'ikal-ladhīna ya'lamullāhu mā fī qulūbihim fa a'rid 'anhum wa'izhum waqul lahum fī anfusihim qawlā balīghā

Those are the ones of whom Allāh knows what is in their hearts, so turn away from them¹⁹⁶ but admonish them and speak to them a far-reaching [i.e., effective] word.
