Surah Az-Zumar 39:65
ﲟ ﲠ ﲡ ﲢ ﲣ ﲤ ﲥ ﲦ ﲧ ﲨ ﲩ ﲪ ﲫ ﲬ
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."
Tafsir of Az-Zumar 39:65
Tafsir
Tafsir Ibn Kathir
Verse range: 39:65
Say: "Do you order me to worship other than Allah O you fools!'' And indeed it has been revealed to you, as it was to those before you: "If you join others in worship with Allah, surely your deeds will be in vain, and you will certainly be among the losers.'' This is like the Ayah:
ولو أشركوا لحبط عنهم ما كانوا يعملون
But if they had joined in worship others with Allah, all that they used to do would have been of no benefit to them. (6:88)
بل الله فاعبد وكن من الشاكرين
