I have been married for three years. My Mahr (dowry) is two thousand dinars, one thousand and five hundred of which is in gold. I sold a portion of this gold and kept the money in my savings account. When my husband knew about this, he gave me a slap on the wrist and, in addition to his father, who accused me of theft and threw me out of the house. Later on, they sent some good people to convince me to return to my husband`s house and I did. However, my father-in-law still insists that I`m a thief and have sold my husband`s gold without seeking his permission first, based on the idea that it is my husband's not mine. What is the ruling of Sharia when the wife deals with her Mahr, be it gold or other?
