The Prophet (May peace be upon him) used to seek refuge in Allah for al-Hasan and al-husain, saying ; I seek refuge for both of you in the perfect words of Allah from every devil and every poisonous thing and from the evil eye which influences. He would then say; your father sought refuge in Allah by them for Ismail and Ishaq. Abu Dawud said; this is a proof of the fact that the Quran is not created.
كَانَ النَّبِيُّ ﷺ يُعَوِّذُ الْحَسَنَ وَالْحُسَيْنَ أُعِيذُكُمَا بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ وَمِنْ كُلِّ عَيْنٍ لاَمَّةٍ ثُمَّ يَقُولُ كَانَ أَبُوكُمْ يُعَوِّذُ بِهِمَا إِسْمَاعِيلَ وَإِسْحَاقَ
