A good wife is considered to be the greatest blessing in this world…
The Messenger of Allah (saws) said: “Men wishes to marry a woman for four reasons: her family, her beauty or her Deen (the practice of Islam.) Catch the one who upholds the Deen, or you will not be able to fulfill all your wishes.
(Sahih Bukhari and Muslim)
Religious women usually treat their husbands well because they do it as piety to Allah.
Abu Hurayrah (radiyAllaahu ‘anhu) narrated: The Messenger of Allah (sallAllaahu ‘alayhi wa sallam) was asked which woman is the best? He (sallAllaahu ‘alayhi wa sallam) said:
“The one who pleases her husband when he looks at her, obeys him when he commands, and does not do anything in terms of herself or his money in a way he does not like.”
The wordings of At-Tabarany are: “A person will not gain something, after embracing Islam, better than a believing woman who pleases him when he looks at her and when he is away, she protects herself and her husband’s money.”
