Is the statement of some women that plucking pubic hair is better than shaving it because it delays hair growth and makes it soft, as opposed to shaving, considered an act of disbelief or a presumption that this is better than the guidance of the Prophet, peace and blessings be upon him?

The statement that plucking pubic hair is better is not an act of disbelief (kufr) nor an impugnment of the Prophet's guidance, peace and blessings be upon him. Rather, scholars have differed regarding the superiority of plucking, shaving, or removing hair with a depilatory (nura). Some consider shaving to be better, while others consider plucking to be better for women. Some have distinguished based on age or the effect of plucking. Furthermore, the questioner suffers from obsessive whispers (waswasah), and the therapist advises her to disregard them.
