سنن ابن ماجه

It was narrated that Ibn ‘Abbas said: “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.’”
