Is it permissible for a woman to conclude her marriage without the approval of her family?
                                No marriage is permissible without the presence of a guardian and two trust worthy witnesses, and the woman whose family had denied her right in getting married to a God-fearing, financially and physically capable man should go to the court.
                             
                        
                            
                                
                                Does an internal examination require ghusl?
                                Ghusl isn't required for making internal examination; however, it invalidates one's fasting. And Allah Knows Best.
                             
                        
                            
                                
                                What is the ruling on working in the construction project of an Islamic bank`s administration building?
                                All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions  There is no sin in working for the bank that declares compliance with the rulings of Sharia, in addition to adhering to the rulings of the supervising Sharia committee in the bank itself. This is provided that the committee consists of righteous, trustworthy, specialized scholars. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is it permissible for the big brother to force his sisters to wear Hijjab (Islamic wear) if their father didn`t do his part in this regard ?
                                All Perfect Praise is due to Allah, The Lord of The Worlds
The father`s attention should be drawn gently and politely, and the sisters should also be reminded with good words since Allah, The Almighty, Says (What means): "O ye who believe! Save yourselves and your families from a Fire whose fuel is Men and Stones." [Al-Tahreem/6]. And Allah Knows Best.
