It is narrated from Sayyiduna Abu Salih (may Allah be pleased with him) that a man from Banu Aslam relates that he was bitten. When he informed the Noble Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) said: If you had recited this supplication in the evening: "A‘udhu bikalimatillahi-t-tammati min sharri ma khalaq" (I seek refuge in the perfect words of Allah from the evil of what He has created), then it would not have harmed you. Suhail says: When any of us was bitten, my father would ask him: Did you recite that supplication? If he replied in the affirmative, it seemed that my father believed that it would not harm him.
