The Prophet (sallAllaahu ‘alayhi wa sallam) used to seek Allah’s protection for his grandsons by saying:
أُعيـذُكُمـا بِكَلِـماتِ اللهِ التّـامَّة، مِنْ كُلِّ شَيْـطانٍ وَهـامَّة، وَمِنْ كُـلِّ عَـيْنٍ لامَّـة
‘U’eethukumaa bikalimaatil-laahit-taammati min kulli shaytaanin wa haammatin, wa min kulli ‘aynin laammatin.
I seek protection for you in the Perfect Words of Allah from every devil and every beast , and from every envious blameworthy eye.
[Al-Bukhari: 4/119
