If she commits some immodest act
If the wife commits some blatant act of immodesty, then the 
Qur`aan Majeed explains the manner in which she should be 
rectified. First she should be counselled with affection, and if 
she still does not heed then you should not sleep with her, and 
if she still does not heed then you are allowed to strike her, but 
not so much as to cause pain. 
Remember that women are a trust upon you and they have 
rights over you. You are obliged by the Shariah to maintain her 
well and provide food, clothing and shelter. 
A wife should be given her own spending money
There are a few pointers to discuss here which Hadhrat 
Moulana Ashraf Ali Thaanwi (rahmatullah alayh) had time and 
again stressed on because there is general negligence and 
heedlessness afforded here. The first point mentioned by 
Hadhrat Moulana is that the husband should not content 
himself with the fact that maintenance on the wife is restricted 
to only food and clothes. Together with food and clothing, he 
should give her some personal spending money which she can 
spend with freedom on whatever she wishes. Some people do 
attend to food and clothes for their wives but pay no attention 
to giving them spending money. 
Hadhrat Moulana said that it is essential that the wife be given 
spending money, because there are many such things which she 
may require, of which she may feel shy to ask for, or she may 
feel it inappropriate to mention. You should give your wife 
some spending money so that she may not have to depend or 
ask someone else if she ever has the need. This is also a part of 
maintenance. Hadhrat Moulana used to say that the man who 
does not give his wife this spending money is committing an 
evil.

Be generous and do not scrounge on spending on your wife
Another point is that when you do spend on your family, then 
spend generously and do not adopt the attitude of feeding them 
just enough so they don’t starve. Practice 
Ihsaan
on them, that 
is, spend generously in accordance to your status. Some people 
may be in some confusion that on the one hand the Shariah 
prohibits and discourages wastage and extravagance and on the 
other hand it exhorts spending freely on one’s household. The 
question may arise as to what reconciliation there is between 
these two?
