Sura al-Anʿām 6:135

قُلْ يَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَامِلٌ فَسَوْفَ تَعْلَمُونَ مَن تَكُونُ لَهُۥ عَٰقِبَةُ ٱلدَّارِ إِنَّهُۥ لَا يُفْلِحُ ٱلظَّٰلِمُونَ

qul yā-qawmi iʿmalū ʿalā makānatikum innī ʿāmilun fa-sawfa taʿlamūna man takūnu lahu ʿāqibatu l-dāri innahu lā yufliḥu l-ẓālimūna

Say: "O my people! Do whatever ye can: I will do (my part): soon will ye know who it is whose end will be (best) in the Hereafter: certain it is that the wrong-doers will not prosper."
