When it comes to the issue of showering while in ihram, there is no prohibition or restriction on the pilgrim in this regard. In fact, it is perfectly permissible for the pilgrim to bathe or wash themselves while in the state of ihram.
This ruling is based on the evidence from the Sunnah of the Prophet Muhammad (peace be upon him). It is well-established that the Prophet (peace be upon him) himself bathed while in ihram. This indicates that there is no harm or prohibition in doing so.
Furthermore, it is important to note that the state of ihram is not a state of impurity or uncleanness. Rather, it is a state of consecration and devotion. Therefore, there is no reason for the pilgrim to refrain from bathing or washing themselves.
It is worth mentioning that while bathing or washing is permissible, it is recommended for the pilgrim to be mindful of conserving water during their stay in the sacred precincts of Makkah and Madinah. This is in line with the teachings of Islam, which encourage moderation and avoiding wastefulness.
There is no religious prohibition on showering or bathing while in ihram. The pilgrim is free to cleanse themselves as needed, while also being mindful of conserving water. May Allah accept the pilgrimage of all those who embark on this blessed journey.
