أَعُوْذُ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ، وَمِنْ كُلِّ عَيْنٍ لَّامَّةٍ

A'oodhu bi kalimaat-illaahit-taammati min kulli shaytaanin, wa haammah, wa min kulli 'aynin laammah

I commend you to the protection of Allah’s perfect words from every devil, vermin, and every evil eye. The Prophet (ﷺ) used to seek Refuge with Allah for Al-Hasan and Al-Husain and say: "Your forefather (i.e. Abraham) used to seek Refuge with Allah for Ishmael and Isaac by reciting the following: (the dua is mentioned above) All believing fathers and mothers should recite these verses in the morning and in the evening, blow their children and make dua. Besides, everyone should recite the dua in the morning and evening for their own protection.
