When the Apostle of Allah (pbuh) entered the toilet, he used to say (before entering) : "O Allah, I seek refuge in thee." This is according to the version of Hammad. 'Abd al-Warith has another version : "I seek refuge in Allah form male and female devils." Explaining the variance of the version Abu Dawud says : Shu'bah on the authority of 'Abd al-'Aziz narrated: "O Allah, I seek refuge in Thee," and sometimes he reported: "I take refuge in Allah." Wuhaib (b. Khalid) (on the authority of 'Abd al-'Aziz) narrated: One should take refuge in Allah.
