Mahr

One date as mahr

Q: Is it permissible to me to ask for 1 date for my mahr? I would like to ask my fiancee to go to the poorest date seller, ask him how
much 1 kg of dates cost (f.e. 10 Dinar) and ask him how many family member he has (f.e. with him included there are 6 people living with him) so my fiancee should multiply the cost of 1kg of dates with the family members (inc. the date seller). f.e. 60 Dinars. So I want my fiancee to pay the date seller 60 Dinars, but take only 1 Date as my mahr and leave the others to the date seller as a sadaqa. I would like to eat the date with my fiancee's mother and my mother, and plant it to a tree (in shaa allah). I also would ask (as part of my mahr) for the surah mulk to get recited by him from his heart.

Is this permissible that he give me this 1 date + reciting one surah under such extraordinary circumstances? Or is the mahr void if I just ask for that?

Mahar

Q: I want to ask about Haqmehar. What is prompt and what is deferred Mahar? And if the word "Ind-ul-talb"which means "on demand" is written on Nikahnama along with deferred mahar. If the husband has paid prompt dower at the time of marriage and then abandon the wife after some months and the wife due to abandonment by husband for more than 2 years is demanding her deferred and ind-ul-talb haq mahar then what are islamic rules about it?

Father in-law taking away the mahr

Q: I am asking this question on behalf of my sister. She got married from two years now and alhamdulillah she is blessed with a girl baby. The problem is she was given 110 ounce of gold as maher. Her father in law is a bad person who has even tried to break their relationship for his personal intrest. In fact he has ego problem. Now he is holding the maher and says its given from my earnings not his sons. My brother in law is now trying to move from house but his father is not helping him financially though he is rich. Kindly let me know what is the status of maher in this situation.
