It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to recite these words and blow over Sayyiduna Hasan and Husayn (may Allah be pleased with them both): «أُعِيذُكُمَا بِكَلِمَةِ اللّٰهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ وَمِنْ كُلِّ عَيْنٍ لَامَّةٍ» "I seek refuge for both of you in the perfect attributes of Allah from every devil and every poisonous creature and from every evil eye." And he used to say, "My father, that is, Ibrahim (peace be upon him), used to recite these same words and blow over his two sons, Isma'il and Ishaq (peace be upon them)."
