Surah Az-Zumar 39:65 — سُورَةُ الزُّمَرِ

وَلَقَدْ أُوحِىَ إِلَيْكَ وَإِلَى ٱلَّذِينَ مِن قَبْلِكَ لَئِنْ أَشْرَكْتَ لَيَحْبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ ٱلْخَٰسِرِينَ ﴿65﴾

And verily it hath been revealed unto thee as unto those before thee (saying): If thou ascribe a partner to Allah thy work will fail and thou indeed wilt be among the losers.

Surah Az-Zumar (The Groups), ayah 65 of 75. Recited by Ahmed ibn Ali al-Ajamy (أحمد بن علي العجمي).
