وَلَقَدْ أُوحِيَ إِلَيْكَ وَإِلَى الَّذِينَ مِن قَبْلِكَ لَئِنْ أَشْرَكْتَ لَيَحْبَطَنَّ عَمَلُكَ وَلَتَكُونَنَّ مِنَ الْخَاسِرِينَ (65)
(39:65) (Tell them clearly that) it was revealed to you and to all Prophets before you: 'If you associate any others with Allah in His Divinity, your works will surely come to naught *74 and you will certainly be among the losers.'
*74) That is, "No act which is performed along with shirk will be adjudged as a righteous act, and no one who, being a mushrik, performs many acts as good acts in his personal judgement, will deserve any reward for them, and his whole life work will be deemed to have gone waste."
