As regards the wife, then her status and her effect in making the soul tranquil and serene, has been clearly shown in the noble aayah (verse), in His - the Most High’s - saying:

...And do not forget about ‘Aaishah - radiyallaahu anhaa - and her great effect. Since even the great Sahaabah (Companions) used to take knowledge of hadeeth from her, and many of the Sahaabiyaat (female Companions) learn the various rulings pertaining to women’s issues from her...

And I have no doubt that my mother - may Allaah shower His mercy upon her - had a tremendous effect upon me, in encouraging me to study; and she assisted me in it. May Allaah greatly increase her reward and reward her with the best of rewards for what she did for me.

And there is no doubt also, that the house in which there is kindness, gentleness, love and care, along with the correct Islaamic tarbiyah (education and cultivation) will greatly affect the man. So he will become - if Allaah wills - successful in his affairs and in any matter - whether it be seeking knowledge, trading, earning a living, or other than this. So it is Allaah alone that I ask to grant success and to guide us all to that which He loves and is pleased with. And may the prayers and peace of Allaah be upon our Prophet Muhammad, and upon his Family, his Companions and his followers.
