Hadith 1535
Ibn ‘Abbas said that God’s messenger used to commend al-Hasan and al-Husain to God’s protection, saying “With God’s perfect words I commend you to God’s protection from every devil and poisonous creature and from every evil eye.” And he would say, “Your ancestor used to commend Ishmael and Isaac with them to God’s protection.”(Abraham is here said to have done to his sons the same as the Prophet did to his grandsons.) Bukhari transmitted it. Most texts of al-Masabih have “with them” in the dual.
وَعَنِ ابْنِ عَبَّاسٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم يعوذ الْحسن وَالْحسن: «أُعِيذُكُمَا بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ كُلِّ شَيْطَانٍ وَهَامَّةٍ وَمِنْ كُلِّ عَيْنٍ لَامَّةٍ» وَيَقُولُ: «إِنَّ أَبَاكُمَا كَانَ يعوذ بهما إِسْمَاعِيلَ وَإِسْحَاقَ» . رَوَاهُ الْبُخَارِيُّ وَفِي أَكْثَرِ نُسَخِ المصابيح: «بهما» على لفظ التَّثْنِيَة
