وَلَقَدْ أُوحِيَ إِلَيْكَ وَإِلَى الَّذِينَ مِنْ قَبْلِكَ لَئِنْ أَشْرَكْتَ لَيَحْبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ الْخَاسِرِينَ

Surah Az-Zumar : 65
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."
