Surah Al-An'am (The Cattle), Verse 135

قُلْ یٰقَوْمِ اعْمَلُوْا عَلٰی مَكَانَتِكُمْ اِنِّیْ عَامِلٌ فَسَوْفَ تَعْلَمُوْنَ مَنْ تَكُوْنُ لَهٗ عَاقِبَةُ الدَّارِ اِنَّهٗ لَا یُفْلِحُ الظّٰلِمُوْنَ ۟

Qul yaa qawmi' maloo 'alaa makaanatikum innee 'aamilun fasawfa ta'lamoona man takoonu lahoo 'aaqibatud daar; innahoo laa yuflihuz zaalimoon

“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."”
