Can husband remove pubic hair of wife according to Islam?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

It is reported by Ahmad , Abu Dawood and al-Tirmizi , from Bahz Ibn Hakeem from his father, from his grandfather that he said: "I said: O Messenger of Allah! Our private parts? What is allowed for us to show and what should we conceal (from the people's eyes)?" He said: "Protect (guard) your private parts except from your wife and from that your right hand possesses, i.e. slave-girls" .

It is lawful for both spouses to get pleasure and satisfaction from each other's genital organs with watching, touching and sexual intercourse.

So, there is no legitimate prohibition regarding removing the hair from the private parts of one's spouse, since more than that is allowed (as we see in upper text).

Allah knows best.
