Verse 65

وَلَقَدْ أُوحِىَ إِلَيْكَ وَإِلَى ٱلَّذِينَ مِن قَبْلِكَ لَئِنْ أَشْرَكْتَ لَيَحْبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ ٱلْخَـٰسِرِينَ

And it has been inspired to you as well as those before you that if you ever set up a partner for god, all your deeds will be nullified and you will end up amongst the losers.
