15. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan and Muhammad ibn Yahya from Muhammad ibn al-Husayn from Safwan ibn Yahya from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “I once asked abu ‘Abd Allah , about slumbering once or twice. He (the Imam) said, ‘I do not know what slumbering once or twice is; however Allah says, “Man is well aware of his soul.” Ali , would say, “If one feels the taste of sleep when standing or sitting, it then becomes necessary for him to take Wudu’.’””
