Surah Az-Zumar, Verse 65

وَلَقَدۡ أُوحِيَ إِلَيۡكَ وَإِلَى ٱلَّذِينَ مِن قَبۡلِكَ لَئِنۡ أَشۡرَكۡتَ لَيَحۡبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ ٱلۡخَٰسِرِينَ٦٥

walaqad ūḥiya ilayka wa-ilā alladhīna min qablika la-in ashrakta layaḥbaṭanna ʿamaluka walatakūnanna mina l-khāsirīna

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