Allah has indeed given this stature of high dignity and respect to every mother for several reasons.
1. She experiences extreme hardship in bearing and in giving birth to the child
2. She provides pre birth and post birth nourishment to the child
3. Mostly, the woman brings her child up and serves the needs of the child day and night
4. She teaches and trains the child.
The education and training during the first few years of a child's life is the determining factor in making his future's personality. True! All great men have great mothers.
Unfortunately, many mothers misuse the privilege and honour accorded to them by Allah. Many mothers take partial or total control of the children and the prefer to follow the dictates of their mother. It makes the father somewhat ineffective. so much that such mothers pitch the children against the father in various family matters.
Men are the protectors and maintenance of women, because Allah has made one of them to excel the other, and because they spend from their means. Therefore the righteous women are devoutly obedient and guard in the husband's absence what Allah ask them to guard (e.g their chastity, their husband's property).
