Kur’an 39:65 — sura Az-Zumar, 65. ajet

وَلَقَدۡ أُوحِيَ إِلَيۡكَ وَإِلَى ٱلَّذِينَ مِن قَبۡلِكَ لَئِنۡ أَشۡرَكۡتَ لَيَحۡبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ ٱلۡخَٰسِرِينَ

A tebi, i onima prije tebe objavljeno je: "Ako budeš druge Allahu ravnim smatrao, tvoja djela će, sigurno, propasti, a ti ćeš izgubljen biti."

And it was already revealed to you and to those before you that if you should associate [anything] with Allah, your work would surely become worthless, and you would surely be among the losers
