2. A number of our people have narrated from Sahl ibn Ziyad Ahmad ibn Muhammad from Hammad ibn ‘Uthaman from Yahya al- Azraq who has said the following: “I once asked abu al-Hassan , about a man who performs three or four times Sa‘y between al-Safa’ and al-Marwah. He then urinates: if he can perform Sa‘y without wudu’. He (the Imam) said, ‘It is not harmful but if he can complete the acts with wudu’, it would be more beloved to me.”
