885 – Ibn ʿAbbās (may Allah be pleased with them both) said: The Messenger of Allah ﷺ stated, “If, when one of you intends to approach his wife, he says, ‘In the name of Allah. O Allah, keep Satan away from us and keep Satan away from whatever You grant us,’ then, should a child be decreed for them from that union, Satan will never harm him.” Agreed upon. (1)

Vocabulary of the ḥadith
• law anna: the particle law here conveys a wish; therefore, according to leading grammarians, it does not require an apodosis.
• ahl-hu (“his family”): plural ahlūn. A man’s ahl are his relatives, as in the verse, “Indeed, my son is of my family” (Hūd 45). In this ḥadith ahl refers specifically to his wife.
• jannibnā (“keep us away”): from jannaba / yujannibu / tajnīban, meaning to remove something and distance it.
• al-shayṭān: morphologically on the pattern fayʿāl from the root shaṭana; the nūn is original according to the sound view. Shayṭān is well known, and every obstinate rebel among humans, jinn, or even animals may be called a shayṭān.
• mā razaqtanā (“that which You have provided for us”): from rizq, plural arzāq. With a kasrah on the rāʾ it is the noun; with a fatḥah it is the verbal noun. In Arabic rizq denotes “share” or “portion,” as in the verse, “and you make your provision that you deny” (al-Wāqiʿah 82). Rizq is a general term for anything from which benefit is derived; hence the prayer, “O Allah, provide me with a righteous wife.” Here it refers to the child that may result from the intercourse.
• lam yaḍurrhu (“he will not be harmed”): with an open rāʾ. The harm is unrestricted, encompassing both religious and physical harm.
