Authentic Supplication Number 254.

Allah the Exalted said in translation: “And if (at any time) an incitement to discord is made to you by shaytan, seek refuge i n Allah, He is the One Who hears and knows all things.” (257).

Sulayman bin Surdin said: I was sitting with the Messenger of Allah  and two men were insulting each other, the face of one of them had become red, and his jugular veins had puffed up, so the Messenger of Allah  said: “I surely know a word, would he have said it, that which he is experiencing would have left him. If he had said: ‘A’outhu bil-lahi minash-shaytanir-rajeemi (258), that which he is experiencing would have gone away from him”.

(257) Surat Fussilat (#41) V. 36.
(258) I solicit Allah’s protection from the despicable shaytan.
