Hire purchase

Q: I live in muscat. I bought my car on hire purchase. The total price of tyre car is 8000 rials but on hire purchase its 8500 rials. So firstly is this halal?
Secondly. Last month I couldn't pay the car installment due to eid and ramadhaan so now they told me that I have to pay 5 rials to postpone that installment in the future so is this halal? The installment will be the same but I will have to pay 5 rials to delay this installment. Is this halal?

Secondly I bought a credit card and if I pay the money used by the card in 52 days then no interest will be charged but I have to pay a small amount
monthly that is for the card not for the money I use from the card so is this halal?

White discharge of women

Q: Could Mufti Saab please advise me on the following masaail regarding the normal (whitish/yellowish) discharge of a woman which she has no control over and which is experienced many times in a day.

1.Will it break her wudhu?

2. Will her wudhu break each time she experiences it even if it occurs 5 times in one salaam time?

3. When will her clothing be regarded as impure?

4. If wudhu does break each time and she was under the impression that the rule of this discharge is the same as the rule of a mazoor will she have to read qadhaas for all the salaahs she may have read in this condition (even when some Ulamaa are of the opinion that this discharge will not break her wudhu)?

5.If Mufti Saab's opinion is that her wudhu will break, how should she maintain radhaa with this fatwah (as it is very difficult to make wudhu so often)?

Zakaat on a joint loan

Q: Myself and my husband had taken a home loan of 12 Lakhs (Joint loan, interest based) in 2006. We got rid of the loan in 2010. To calculate my Zakat for these years, should I deduct my assets from 12 lakhs or 6 lakhs? For 3 years I was paying whole of the installment, 4th year onwards both of us paid half and half.
