Satan, our greatest enemy, is invisible. This makes it easy to forget the threat that he and all the devils pose to us. How do we keep this constant threat in mind and remain vigilant? We can start by remaining aware of our own temptations and seeking refuge in the words of God: "My Lord, I seek refuge in You from the strokes of the devils, and I seek refuge in You, my Lord, lest they come close to us." [23:97-98]

وَقُل رَّبِّ أَعُوذُ بِكَ مِنْ هَمَزَاتِ الشَّيَاطِين
وَأَعُوذُ بِكَ رَبِّ أَن يَحْضُرُون

waqul rabbi aʿūdhu bika min hamazāti l-shayāṭīn. wa-aʿūdhu bika rabbi an yaḥḍurūn
