فَزَيَّنَ لَهُمُ الشَّيْطَانُ أَعْمَالَهُمْ
Reflect on this ayah, “Shaitan beautified their actions to them…” [Surat An-Nahl: 63]
This doesn’t only apply to haram actions like adultery, drugs, and alcohol. This ayah also means something else. When you are doing the work of Islam—da’wah, praying, fasting—but you are doing it for the wrong reasons, shaitan beautifies that, too. Because he doesn’t care about the deed, he only cares that your heart should be corrupt.
