Q: I would like to know if I can speak to my wife by implanting thoughts in her mind to love me without her realizing this consciously to improve my marriage. These techniques are taught in NLP Neuro-linguistic programming which teaches people how to use language to influence others by saying a sentence in a way where you are telling the mind what to do. For example, instead of saying you should love me, I said to her you can feel yourself loving me more and more now. Is this permissible for me to do?

Q: If a husband wife don't have sex for 5-6 months or more after their child was born, will it affect their nikaah in any way? They eat and sleep together and they both are happy with only one child. Somebody said that if they don't have sex for a long time it will affect their nikaah.

Q: Are women like slaves of their husband in Islam? I have come across some writings where some quotations were mentioned supporting this. One quotation was on Umar (radhiyallahu anhu). It was something that women are like slaves of their husbands. So be careful whom you are giving your daugter to as a slave. Is it true?

In many places I have read that the hoors are getting angry on a wife who is upsetting the husband or disobeying him and they curse the wife. Are these all true? Are all women born slaves of men?
