Salam and Peace!
A man is incomplete without a woman.
A woman is incomplete without a man.
Man is a supplement to the woman.
Woman is a supplement to the man.
When they come together and supplement each other, they bear fruit.
A wife is also a life-partner.
Your life-partner is not your mother, father, brother, sister, daughter, or anyone else,----but the woman you marry.
She is your better half. She is your life-partner. She is your supplement.
She is your wife.
And most importantly,---she is absolutely equal to you in status, importance, witness, iman, deeds, etc.
There was one thing in the beginning. Allah made it two. One is man. The other one is woman.
According to Al-Quran:
Man and woman are equal.-----Companions!
A husband is a servant to his wife, and a wife is obedient to her husband.
No one is a master.
One is servant, and the other is obedient.
