What to say to foil the devil's plots
Aʿūdhu bkalimāti llāhi at-tāmmāti allatī lā yujāwizuhunna barrun walā fājirun: min sharri mā khalaqa, wa baraʾa wa dharaʾa, wamin sharri mā yanzilu mina as-samāʾi, wamin sharri mā yaʿruju fyhā, wamin sharri mā dharaʾa fī l-ʾarḍi, wamin sharri mā yakhruju minhā, wamin sharri fitani l-layli wa an-nahāri, wamin sharri kulli ṭāriqin illā ṭāriqan yaṭruqu bi-khayrin yā raḥmān
I take refuge within Allah’s perfect words which no righteous or unrighteous person can transgress, from all the evil that He has created, made and originated. I take refuge from the evil that descends from the sky and the evil that rises up to it. I take refuge from the evil that is spread on Earth and the evil that springs from her, and I take refuge from the evil of the tribulations of night and day, and the evil of one who visits at night except the one who brings good, O Merciful One.
