Condition for the validity of nikaah

Q: In my area the Shariah is not applied to its extent. My question is regarding marriage. There are many so called Muslims getting married according to the customs of this area which is not in compliance wih Shariah. People roam freely to choose and meet there life partners instead of the Shariah compliant way. Will these marriages be cosidered as Legal according Shariah?

Parents bickering and arguing

Q: My parents are always bickering and arguing, talking about leaving each other, making a dull atmosphere in the house. I am 16 and I have two younger brothers of 13 and 6. They are happy at times and they will love each other. Is there any dua I can read to stop the arguing?

How to spend one's salary

Q: I would like to know if there is any guidelines in the shari'ah on how one should spend their money/salary. Someone told me that it was the advice of one of the ulama that your income/salary should be divided into 3 parts:

  1. Charity ie discharging zakaat, qurbani and spending on ones parents etc
  2. For your living essentials and spending.
  3. Savings

What is muftis opinion on the above? Also I would like to know if a person can stop doing the above with no valid reason?
