Imam as-Sadiq (a) said: "The well-qualified husband is the chaste who can save good living." 467

The ideal wife is the faithful, chaste, highborn, well-mannered, good-looking woman who is well-behaved with her husband.
The Prophet (s) said: "The best of your ladies are the fertile, the amiable, the chaste, the proud with her family, the humble with her husband, who adorns herself for her husband, behaves decently with others, listens and carries out her husbands' instructions, provides herself for him when they are alone, and avoids violating good manners, like men.
The worst of your ladies are the humble with her family and proud against her husband, the barren, the spiteful, who does not care if she does something hideous, adorns herself when her husband is absent, behaves chastely with him when he is present, does not listen and does not carry out his instructions, abstains from providing herself to him when they are alone just like a riding animal that prevents the rider
