This is further supported by the jurists’ own statement: if a man puts on the leather socks while resident, then becomes ritually impure, then travels, and wipes over them for the first time while travelling, he completes the wiping period of a traveller (1). This clearly indicates that they reckon the beginning of the period from the time of wiping.

Thus, the correct view is that what counts is the wiping, not the occurrence of ritual impurity.

For example, a man performs ablution for the dawn prayer and puts on the leather socks, remaining in a state of purity until nine o’clock in the forenoon. He then becomes ritually impure but does not renew his ablution until twelve o’clock. According to the school’s position, the period begins at nine o’clock.

According to the preponderant view, it begins at twelve o’clock and lasts until that same time on the following day if he is resident, or on the fourth day if he is travelling.
