إِيَّاكَ وَالتَّنَعُّمَ، فَإِنَّ عِبَادَ اللَّهِ لَيْسُوا بِالْمُتَنَعِّمِينَ
Beware of indulgent luxury, for the servants of Allah are not people given over to indulgence.

إِيَّاكَ is a warning expression meaning “beware.” التَّنَعُّمَ here points to overindulgence in comfort and luxury. فَإِنَّ supplies a reason with emphasis, while الْمُتَنَعِّمِينَ describes those given over to luxurious living.
This is not a blanket rejection of all lawful comfort or enjoyment of blessings. The warning is against making indulgence the organizing goal of life so that worship, gratitude, duties, and other people’s rights become secondary.
