Is it impermissible, according to the Shafi'is, to shave one's hair outside the Hajj seasons?

The later Shafi'is consider shaving the beard مکروه (reprehensible), whether during rituals (نسك) or otherwise. This is contrary to what Ibn al-Rif'ah transmitted from al-Shafi'i in "Al-Umm," namely, that he explicitly stated its prohibition. The same view was held by al-Halimi and al-Qaffal al-Shashi. Al-Adhra'i held the view that shaving it is absolutely forbidden unless there is a valid reason.
