أُعِيذُكَ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ وَمِنْ كُلِّ عَيْنٍ لَامَّةٍ
To soothe children during illness or at any harm recite:
“I seek refuge in Allah with His total words from the evil Satan, from every poisonous animal and from the evil eye”. (Bukhari)
If any member of Prophet Mohammad (SAW.)’s household fell ill, he used to recite the the four Quls and blow on them.
