Assisting one’s wife in household chores does not emasculate a husband. Rather, it is from the righteous characteristics that emulate the noble Prophet (ﷺ).
Imām al-Bukhārī reported that al-Aswad said: “I asked ʿĀishah (رضي الله عنها): ‘What did the Prophet (ﷺ) use to do inside his house?’ She answered: ‘He use to keep himself busy serving the members of his family, and when it was time for the prayer, he would leave.” Ḥadīth (676) and (5363)
‘Serving the members of his family’ meaning, assisting them in the different tasks that were binding upon them.
Note: There has come in some narrations a description of some of the things that he (ﷺ) would do in the house. ʿUrwah said: “I said to ʿĀiʾshah (رضي الله عنها): ‘O Mother of the Believers! What did the Prophet (ﷺ) use to do when he was with you?’ She said: ‘He would do what any of you would do when serving the members of your family. He would mend his sandals, sew his thowb, and patch his bucket.”
