Contributions of the Muslim Woman in giving finance Advice

Allāh says,
“They are your cover, and you are their cover.” [Sūrah al-Baqarah 2:187]
Ibn Kathīr commented,
“In short, the wife and the husband are intimate and have sexual intercourse with each other.”
If that is so, there is no doubt that the wife knows her husband more than anybody else. She knows his true character, traits, morals, worship, commitment to obedience, and she can advise him whenever she notices negligence in his religious commitment or his integrity. This makes her a huge support for him in worshipping Allāh and getting closer to Him, and the only way to achieve this is by offering her advice since people with closer relations are more entitled to the advice than those with far relations; and who is closer to the husband than his wife?!
ʿĀishah (may Allāh be pleased with her) used to teach women and instruct them to advise their husbands. Muʿādhah narrated that ʿĀishah said:
“Tell your husbands to clean themselves with water, for I am too shy to tell them myself. The Messenger of Allāh (Sallallahu ‘Alayhi wa Sallam) used to do that.”
