WE RELATE FROM the Ṣaḥīḥ of al-Bukhārī that Ibn ‘Abbās 
reported that the Messenger of Allah 
said: “If any one of you goes to his wife and says: ‘In the name of Allah. O Allah, protect us from Shayṭān and keep Shayṭān away from what You have provided us,’ if a child is decreed for them Shayṭān will not harm him.” [1].According to another report by al-Bukhārī he said, “Shayṭān will never harm him.”

Bismi-llāh, Allāhumma jannibna-sh-Shayṭān, wa jannibi-sh-Shayṭāna mā razaqtanā.
