“””After one month of marriage Mirza Mehmood sent his son Mirza Nasir to England for higher studies. During this period newly wed Mansoora Begum has faced the situation with great patience and courage. She did not mention of her pain to anyone else.
Once she did not receive money from Mirza Mahmood for his daily expenditures. She wanted to send a letter to her husband in England but had no money to pay postal charges. She was so self honoured a lady that she did not ask for the money even from her parents. So she took one of relative into confidence and sold the real silver or gold embroidery (suchha Gota) of her Dupatta.”””
