The Prophet (ﷺ) sought salvation for Hasan-Hussein (grandchildren) in this way:

أُعِيْذُكُمَا بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَّهَامَّةٍ وَّمِنْ كُلِّ عَيْنٍ لَامَّةٍ

U'eethukumaa bikalimaatil-laahit-taammati min kulli shaytaanin wa haammah, wa min kulli 'aynin laammah

I seek protection for you in the Perfect Words of Allah from every devil and every beast, and from every envious blameworthy eye.
