Surah Al-Falaq (three times)

بِسۡمِ ٱللَّهِ ٱلرَّحۡمَٰنِ ٱلرَّحِيمِ قُلۡ أَعُوذُ بِرَبِّ ٱلۡفَلَقِ مِن شَرِّ مَا خَلَقَ وَمِن شَرِّ غَاسِقٍ إِذَا وَقَبَ وَمِن شَرِّ ٱلنَّفَّٰثَٰتِ فِي ٱلۡعُقَدِ وَمِن شَرِّ حَاسِدٍ إِذَا حَسَدَ

Bismillaahir-Rahmaanir-Raheem. Qul a'oodhu bi-Rabbil-falaq, min sharri maa khalaq, wa min sharri ghaasiqin idhaa waqab, wa min sharrin-naffaathaati fil-'uqad, wa min sharri haasidin idhaa hasad

In the name of Allah, the Beneficent, the Merciful Say: I seek refuge in the Lord of the Daybreak From the evil of that which He created From the evil of the darkness when it is intense And from the evil of malignant witchcraft And from the evil of the envier when he envieth

Qur'an 113:1-5 (Al-Falaq)
