It was narrated that Ibn 'Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) used to seek refuge with Allah for al-Hasan and al-Husain, saying: “I seek refuge for you in the perfect words of Allah from every devil and poisonous reptile, and from every envious evil eye.” Then he would say: "This is how my father Ibraheem used to seek refuge for Isma'eel and Ishaq (عليهما السلام)."
