Question
When someone wipes over their khuffs and then sleeps after the wiping, when does the counting of the duration for wiping over the khuffs begin?
Answer
I say, and with God's success: Its first duration is from the beginning of the sleep time, not from the moment of awakening; because sleep nullifies ablution, so does wiping. See: Tanweer al-Absar and Al-Durr al-Mukhtar and Rad al-Mukhtar 1: 185, and Al-Hadiyya al-Alaiyya p. 40, and God knows best.
