Musnad Ahmad 25:576

'Abd al-Razzaq narrated to us, Sufyan informed us, from Mansur, from al-Minhal ibn 'Amr, from Sa'id ibn Jubayr, from Ibn 'Abbas, who said: The Messenger of Allah (may Allah bless him and grant him peace) used to seek refuge for al-Hasan and al-Husayn, saying: "I seek refuge for you both with the perfect word of Allah from every devil and every poisonous creature, and from every evil eye." Then he would say: "Thus did my father Ibrahim (peace be upon him) seek refuge for Isma'il and Ishaq (peace be upon them)."
