My headcloth is causing me a terrible headache and severe shortsightedness. Is it permissible for me to take it off?
                                All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
If the headcloth Khimar is harmful, it is sufficient to wear the Niqab (face-veil). However, with the passage of time you will get used to the Khimar and these symptoms will go away. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                I joined a savings club and was scheduled to receive the payout first. My friend asked to take my place in line, so I requested 50 dinars in exchange for letting her have my turn. What is the ruling on this?
 
 
 
 
 
                                This is impermissible, as it involves taking money without providing something of value in return according to Islamic law. And Allah The Almighty Knows Best.
                             
                        
                            
                                
                                Is it permissible for a wife`s family to demand her husband to divorce her although she doesn`t want that?
                                It is forbidden for them to do that in case their daughter doesn`t want divorce unless there was a sin that continues as long as the marriage survives.
                             
                        
                            
                                
                                Is it permissible for the woman to use her mobile phone while on the street?
                                All Perfect Praise is due to Allah, The Lord of The Worlds 
Modesty should be observed by the woman at all times, so she is free to use her phone while on the street as long as it is done within the limits of Islamic manners. And Allah The Almigty Knows Best.
