Surah Al-Mujadilah (The Pleading Woman), Verse 10

اِنَّمَا النَّجْوٰی مِنَ الشَّیْطٰنِ لِیَحْزُنَ الَّذِیْنَ اٰمَنُوْا وَلَیْسَ بِضَآرِّهِمْ شَیْـًٔا اِلَّا بِاِذْنِ اللّٰهِ وَعَلَی اللّٰهِ فَلْیَتَوَكَّلِ الْمُؤْمِنُوْنَ ۟

Innaman najwaa minash shaitaani liyahzunal lazeena aamanoo wa laisa bidaaarrihim shai'an illaa bi-iznil laah; wa 'alal laahi falyatawakkalil mu'minoon

“Secret counsels are only (inspired) by the Evil One, in order that he may cause grief to the Believers; but he cannot harm them in the least, except as Allah permits; and on Allah let the Believers put their trust.”

Quran 58:10 (Yusuf Ali Translation)
