Du’aa: “My Lord! I seek refuge with You from the whisperings of the Shayaateen”
Rabbi ‘a`outhubika min hamazaatish-shayaateeni, wa ‘a`outhu bika rabbi ‘ay-yahdhuroon
“My Lord! I seek refuge with You from the whisperings of the Shayaateen. And I seek refuge with You, My Lord! lest they should come near me.”
(Surah Al Muminoon 23:97-98)
Tafseer Ibn Katheer :
(And say: “My Lord! I seek refuge with You from the whisperings of the Shayatin.”) Allah commanded him to seek refuge with Him from the Shayatin, because no trick could help you against them and you cannot protect yourself by being kind to them. We have already stated, when discussing Isti`adhah (seeking refuge), that the Messenger of Allah used to say,‘A`outhu bil lãhi ‘as-samee`il-`aleemi minash-shaytãnir-rajeemi, min hamzihi, wa naphkhihi, wa nafthihi
I seek refuge with Allah, the All-Hearing, All-Knowing, from the accursed Shayatin, from his whisperings, evil suggestions and insinuations.
(“And I seek refuge with You, My Lord! lest they should come near me.”) means, in any issue of my life. So we are commanded to mention Allah at the beginning of any undertaking, in order to ward off the Shayatin at the time of eating, intercourse, slaughtering animals for food, etc.
