Sayyidi wa sanadi Shaykh Mufti Mohammad Taqi Usmani (may Allah preserve him) said:

“My respected father Hadhrat Mufti Mohammad Shafii’ (amy Allah have mercy on him) used to say that the healthy and happy relations between husband and wife are not at all possible unless they have taqwa: the fear of Allah, in their heart.

The degree of intimacy between them can never be found in any other relationship. Both are sharing one another’s secrets and are so close to each other that a closer relationship can never be imagined of. These relations are such that they can not be known to others in detail. Under such conditions, when they are in private and intimate, if one partner decides to hurt the other or disregard his/her rights who is going to stop him/her?

There are many rights if they are not executed, one can report to the police or claim them through the court. But most of the rights of husband and wife are such that they can not be reported to the police or be demanded via court. The judicial system at the most will make it possible to claim for wife’s monetary allowance and meher but what about the husband’s arrogant attitude and bitter speech? Which court or police is going to reimburse for these hurtful things?

There is only one thing that can prevent these hurtful things from happening. It is the fear of Allah (taqwa).

That is, when the husband realizes that Allah by uniting his wife to him (via nikah) has imposed some rights for her. These are obligations for me to fulfill. I am bound to undertake them. If I do not comply with them I will be accountable before Allah.
Until this realization arises one can not discharge other’s (marital) rights thoroughly.
