“The Prophet ﷺ used to seek refuge for Hasan and Husain and say: A’udhu bi kalimatil-lahil- tammati, min kulli shaitanin wa hammah, wa min kulli ‘aynin lammah (I seek refuge for you both in the Perfect Words of Allah, from every devil and every poisonous reptile, and from every evil eye).’ And he would say: ‘Thus Ibrahim used to seek refuge with Allah for Isma’il and Ishaq,’ or he said: ‘for Isma’il and Ya’qub.’” (Using translation from Ibn Mājah 3525)
كَانَ النَّبِيُّ ﷺ يُعَوِّذُ الْحَسَنَ وَالْحُسَيْنَ يَقُولُ «أُعِيذُكُمَا بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ وَمِنْ كُلِّ عَيْنٍ لَامَّةٍ» ثُمَّ يَقُولُ «هَكَذَا كَانَ يُعَوِّذُ إِبْرَاهِيمُ ابْنَيْهِ إِسْمَاعِيلَ وَإِسْحَاقَ»
